File: cvs.info, Node: commit options, Next: commit examples, Up: commit commit options -------------- These standard options are supported by `commit' (*note Common options::, for a complete description of them): `-l' Local; run only in current working directory. `-n' Do not run any module program. `-R' Commit directories recursively. This is on by default. `-r REVISION' Commit to REVISION. REVISION must be either a branch, or a revision on the main trunk that is higher than any existing revision number (*note Assigning revisions::). You cannot commit to a specific revision on a branch. `commit' also supports these options: `-F FILE' Read the log message from FILE, instead of invoking an editor. `-f' Note that this is not the standard behavior of the `-f' option as defined in *Note Common options::. Force CVS to commit a new revision even if you haven't made any changes to the file. If the current revision of FILE is 1.7, then the following two commands are equivalent: $ cvs commit -f FILE $ cvs commit -r 1.8 FILE The `-f' option disables recursion (i.e., it implies `-l'). To force CVS to commit a new revision for all files in all subdirectories, you must use `-f -R'. `-m MESSAGE' Use MESSAGE as the log message, instead of invoking an editor. File: cvs.info, Node: commit examples, Prev: commit options, Up: commit commit examples --------------- Committing to a branch ...................... You can commit to a branch revision (one that has an even number of dots) with the `-r' option. To create a branch revision, use the `-b' option of the `rtag' or `tag' commands (*note Branching and merging::). Then, either `checkout' or `update' can be used to base your sources on the newly created branch. From that point on, all `commit' changes made within these working sources will be automatically added to a branch revision, thereby not disturbing main-line development in any way. For example, if you had to create a patch to the 1.2 version of the product, even though the 2.0 version is already under development, you might do: $ cvs rtag -b -r FCS1_2 FCS1_2_Patch product_module $ cvs checkout -r FCS1_2_Patch product_module $ cd product_module [[ hack away ]] $ cvs commit This works automatically since the `-r' option is sticky. Creating the branch after editing ................................. Say you have been working on some extremely experimental software, based on whatever revision you happened to checkout last week. If others in your group would like to work on this software with you, but without disturbing main-line development, you could commit your change to a new branch. Others can then checkout your experimental stuff and utilize the full benefit of CVS conflict resolution. The scenario might look like: [[ hacked sources are present ]] $ cvs tag -b EXPR1 $ cvs update -r EXPR1 $ cvs commit The `update' command will make the `-r EXPR1' option sticky on all files. Note that your changes to the files will never be removed by the `update' command. The `commit' will automatically commit to the correct branch, because the `-r' is sticky. You could also do like this: [[ hacked sources are present ]] $ cvs tag -b EXPR1 $ cvs commit -r EXPR1 but then, only those files that were changed by you will have the `-r EXPR1' sticky flag. If you hack away, and commit without specifying the `-r EXPR1' flag, some files may accidentally end up on the main trunk. To work with you on the experimental change, others would simply do $ cvs checkout -r EXPR1 whatever_module File: cvs.info, Node: diff, Next: export, Prev: commit, Up: CVS commands diff--Show differences between revisions ======================================== * Synopsis: diff [-lR] [format_options] [[-r rev1 | -D date1] [-r rev2 | -D date2]] [files...] * Requires: working directory, repository. * Changes: nothing. The `diff' command is used to compare different revisions of files. The default action is to compare your working files with the revisions they were based on, and report any differences that are found. If any file names are given, only those files are compared. If any directories are given, all files under them will be compared. The exit status for diff is different than for other CVS commands; for details *Note Exit status::. * Menu: * diff options:: diff options * diff examples:: diff examples File: cvs.info, Node: diff options, Next: diff examples, Up: diff diff options ------------ These standard options are supported by `diff' (*note Common options::, for a complete description of them): `-D DATE' Use the most recent revision no later than DATE. See `-r' for how this affects the comparison. `-k KFLAG' Process keywords according to KFLAG. See *Note Keyword substitution::. `-l' Local; run only in current working directory. `-R' Examine directories recursively. This option is on by default. `-r TAG' Compare with revision TAG. Zero, one or two `-r' options can be present. With no `-r' option, the working file will be compared with the revision it was based on. With one `-r', that revision will be compared to your current working file. With two `-r' options those two revisions will be compared (and your working file will not affect the outcome in any way). One or both `-r' options can be replaced by a `-D DATE' option, described above. The following options specify the format of the output. They have the same meaning as in GNU diff. -0 -1 -2 -3 -4 -5 -6 -7 -8 -9 --binary --brief --changed-group-format=ARG -c -C NLINES --context[=LINES] -e --ed -t --expand-tabs -f --forward-ed --horizon-lines=ARG --ifdef=ARG -w --ignore-all-space -B --ignore-blank-lines -i --ignore-case -I REGEXP --ignore-matching-lines=REGEXP -h -b --ignore-space-change -T --initial-tab -L LABEL --label=LABEL --left-column -d --minimal -N --new-file --new-line-format=ARG --old-line-format=ARG --paginate -n --rcs -s --report-identical-files -p --show-c-function -y --side-by-side -F REGEXP --show-function-line=REGEXP -H --speed-large-files --suppress-common-lines -a --text --unchanged-group-format=ARG -u -U NLINES --unified[=LINES] -V ARG -W COLUMNS --width=COLUMNS File: cvs.info, Node: diff examples, Prev: diff options, Up: diff diff examples ------------- The following line produces a Unidiff (`-u' flag) between revision 1.14 and 1.19 of `backend.c'. Due to the `-kk' flag no keywords are substituted, so differences that only depend on keyword substitution are ignored. $ cvs diff -kk -u -r 1.14 -r 1.19 backend.c Suppose the experimental branch EXPR1 was based on a set of files tagged RELEASE_1_0. To see what has happened on that branch, the following can be used: $ cvs diff -r RELEASE_1_0 -r EXPR1 A command like this can be used to produce a context diff between two releases: $ cvs diff -c -r RELEASE_1_0 -r RELEASE_1_1 > diffs If you are maintaining ChangeLogs, a command like the following just before you commit your changes may help you write the ChangeLog entry. All local modifications that have not yet been committed will be printed. $ cvs diff -u | less File: cvs.info, Node: export, Next: history, Prev: diff, Up: CVS commands export--Export sources from CVS, similar to checkout ==================================================== * Synopsis: export [-flNnR] [-r rev|-D date] [-k subst] [-d dir] module... * Requires: repository. * Changes: current directory. This command is a variant of `checkout'; use it when you want a copy of the source for module without the CVS administrative directories. For example, you might use `export' to prepare source for shipment off-site. This command requires that you specify a date or tag (with `-D' or `-r'), so that you can count on reproducing the source you ship to others (and thus it always prunes empty directories). One often would like to use `-kv' with `cvs export'. This causes any keywords to be expanded such that an import done at some other site will not lose the keyword revision information. But be aware that doesn't handle an export containing binary files correctly. Also be aware that after having used `-kv', one can no longer use the `ident' command (which is part of the RCS suite--see ident(1)) which looks for keyword strings. If you want to be able to use `ident' you must not use `-kv'. * Menu: * export options:: export options File: cvs.info, Node: export options, Up: export export options -------------- These standard options are supported by `export' (*note Common options::, for a complete description of them): `-D DATE' Use the most recent revision no later than DATE. `-f' If no matching revision is found, retrieve the most recent revision (instead of ignoring the file). `-l' Local; run only in current working directory. `-n' Do not run any checkout program. `-R' Export directories recursively. This is on by default. `-r TAG' Use revision TAG. In addition, these options (that are common to `checkout' and `export') are also supported: `-d DIR' Create a directory called DIR for the working files, instead of using the module name. *Note checkout options::, for complete details on how CVS handles this flag. `-k SUBST' Set keyword expansion mode (*note Substitution modes::). `-N' Only useful together with `-d DIR'. *Note checkout options::, for complete details on how CVS handles this flag. File: cvs.info, Node: history, Next: import, Prev: export, Up: CVS commands history--Show status of files and users ======================================= * Synopsis: history [-report] [-flags] [-options args] [files...] * Requires: the file `$CVSROOT/CVSROOT/history' * Changes: nothing. CVS can keep a history file that tracks each use of the `checkout', `commit', `rtag', `update', and `release' commands. You can use `history' to display this information in various formats. Logging must be enabled by creating the file `$CVSROOT/CVSROOT/history'. *Warning:* `history' uses `-f', `-l', `-n', and `-p' in ways that conflict with the normal use inside CVS (*note Common options::). * Menu: * history options:: history options File: cvs.info, Node: history options, Up: history history options --------------- Several options (shown above as `-report') control what kind of report is generated: `-c' Report on each time commit was used (i.e., each time the repository was modified). `-e' Everything (all record types). Equivalent to specifying `-x' with all record types. Of course, `-e' will also include record types which are added in a future version of CVS; if you are writing a script which can only handle certain record types, you'll want to specify `-x'. `-m MODULE' Report on a particular module. (You can meaningfully use `-m' more than once on the command line.) `-o' Report on checked-out modules. This is the default report type. `-T' Report on all tags. `-x TYPE' Extract a particular set of record types TYPE from the CVS history. The types are indicated by single letters, which you may specify in combination. Certain commands have a single record type: `F' release `O' checkout `E' export `T' rtag One of four record types may result from an update: `C' A merge was necessary but collisions were detected (requiring manual merging). `G' A merge was necessary and it succeeded. `U' A working file was copied from the repository. `W' The working copy of a file was deleted during update (because it was gone from the repository). One of three record types results from commit: `A' A file was added for the first time. `M' A file was modified. `R' A file was removed. The options shown as `-flags' constrain or expand the report without requiring option arguments: `-a' Show data for all users (the default is to show data only for the user executing `history'). `-l' Show last modification only. `-w' Show only the records for modifications done from the same working directory where `history' is executing. The options shown as `-options ARGS' constrain the report based on an argument: `-b STR' Show data back to a record containing the string STR in either the module name, the file name, or the repository path. `-D DATE' Show data since DATE. This is slightly different from the normal use of `-D DATE', which selects the newest revision older than DATE. `-f FILE' Show data for a particular file (you can specify several `-f' options on the same command line). This is equivalent to specifying the file on the command line. `-n MODULE' Show data for a particular module (you can specify several `-n' options on the same command line). `-p REPOSITORY' Show data for a particular source repository (you can specify several `-p' options on the same command line). `-r REV' Show records referring to revisions since the revision or tag named REV appears in individual RCS files. Each RCS file is searched for the revision or tag. `-t TAG' Show records since tag TAG was last added to the history file. This differs from the `-r' flag above in that it reads only the history file, not the RCS files, and is much faster. `-u NAME' Show records for user NAME. `-z TIMEZONE' Show times in the selected records using the specified time zone instead of UTC. File: cvs.info, Node: import, Next: log, Prev: history, Up: CVS commands import--Import sources into CVS, using vendor branches ====================================================== * Synopsis: import [-options] repository vendortag releasetag... * Requires: Repository, source distribution directory. * Changes: repository. Use `import' to incorporate an entire source distribution from an outside source (e.g., a source vendor) into your source repository directory. You can use this command both for initial creation of a repository, and for wholesale updates to the module from the outside source. *Note Tracking sources::, for a discussion on this subject. The REPOSITORY argument gives a directory name (or a path to a directory) under the CVS root directory for repositories; if the directory did not exist, import creates it. When you use import for updates to source that has been modified in your source repository (since a prior import), it will notify you of any files that conflict in the two branches of development; use `checkout -j' to reconcile the differences, as import instructs you to do. If CVS decides a file should be ignored (*note cvsignore::), it does not import it and prints `I ' followed by the filename (*note import output::, for a complete description of the output). If the file `$CVSROOT/CVSROOT/cvswrappers' exists, any file whose names match the specifications in that file will be treated as packages and the appropriate filtering will be performed on the file/directory before being imported. *Note Wrappers::. The outside source is saved in a first-level branch, by default 1.1.1. Updates are leaves of this branch; for example, files from the first imported collection of source will be revision 1.1.1.1, then files from the first imported update will be revision 1.1.1.2, and so on. At least three arguments are required. REPOSITORY is needed to identify the collection of source. VENDORTAG is a tag for the entire branch (e.g., for 1.1.1). You must also specify at least one RELEASETAG to identify the files at the leaves created each time you execute `import'. Note that `import' does _not_ change the directory in which you invoke it. In particular, it does not set up that directory as a CVS working directory; if you want to work with the sources import them first and then check them out into a different directory (*note Getting the source::). * Menu: * import options:: import options * import output:: import output * import examples:: import examples File: cvs.info, Node: import options, Next: import output, Up: import import options -------------- This standard option is supported by `import' (*note Common options::, for a complete description): `-m MESSAGE' Use MESSAGE as log information, instead of invoking an editor. There are the following additional special options. `-b BRANCH' See *Note Multiple vendor branches::. `-k SUBST' Indicate the keyword expansion mode desired. This setting will apply to all files created during the import, but not to any files that previously existed in the repository. See *Note Substitution modes::, for a list of valid `-k' settings. `-I NAME' Specify file names that should be ignored during import. You can use this option repeatedly. To avoid ignoring any files at all (even those ignored by default), specify `-I !'. NAME can be a file name pattern of the same type that you can specify in the `.cvsignore' file. *Note cvsignore::. `-W SPEC' Specify file names that should be filtered during import. You can use this option repeatedly. SPEC can be a file name pattern of the same type that you can specify in the `.cvswrappers' file. *Note Wrappers::. File: cvs.info, Node: import output, Next: import examples, Prev: import options, Up: import import output ------------- `import' keeps you informed of its progress by printing a line for each file, preceded by one character indicating the status of the file: `U FILE' The file already exists in the repository and has not been locally modified; a new revision has been created (if necessary). `N FILE' The file is a new file which has been added to the repository. `C FILE' The file already exists in the repository but has been locally modified; you will have to merge the changes. `I FILE' The file is being ignored (*note cvsignore::). `L FILE' The file is a symbolic link; `cvs import' ignores symbolic links. People periodically suggest that this behavior should be changed, but if there is a consensus on what it should be changed to, it doesn't seem to be apparent. (Various options in the `modules' file can be used to recreate symbolic links on checkout, update, etc.; *note modules::.) File: cvs.info, Node: import examples, Prev: import output, Up: import import examples --------------- See *Note Tracking sources::, and *Note From files::. File: cvs.info, Node: log, Next: rdiff, Prev: import, Up: CVS commands log--Print out log information for files ======================================== * Synopsis: log [options] [files...] * Requires: repository, working directory. * Changes: nothing. Display log information for files. `log' used to call the RCS utility `rlog'. Although this is no longer true in the current sources, this history determines the format of the output and the options, which are not quite in the style of the other CVS commands. The output includes the location of the RCS file, the "head" revision (the latest revision on the trunk), all symbolic names (tags) and some other things. For each revision, the revision number, the author, the number of lines added/deleted and the log message are printed. All times are displayed in Coordinated Universal Time (UTC). (Other parts of CVS print times in the local timezone). *Warning:* `log' uses `-R' in a way that conflicts with the normal use inside CVS (*note Common options::). * Menu: * log options:: log options * log examples:: log examples File: cvs.info, Node: log options, Next: log examples, Up: log log options ----------- By default, `log' prints all information that is available. All other options restrict the output. `-b' Print information about the revisions on the default branch, normally the highest branch on the trunk. `-d DATES' Print information about revisions with a checkin date/time in the range given by the semicolon-separated list of dates. The date formats accepted are those accepted by the `-D' option to many other CVS commands (*note Common options::). Dates can be combined into ranges as follows: `D1<D2' `D2>D1' Select the revisions that were deposited between D1 and D2. `<D' `D>' Select all revisions dated D or earlier. `D<' `>D' Select all revisions dated D or later. `D' Select the single, latest revision dated D or earlier. The `>' or `<' characters may be followed by `=' to indicate an inclusive range rather than an exclusive one. Note that the separator is a semicolon (;). `-h' Print only the name of the RCS file, name of the file in the working directory, head, default branch, access list, locks, symbolic names, and suffix. `-l' Local; run only in current working directory. (Default is to run recursively). `-N' Do not print the list of tags for this file. This option can be very useful when your site uses a lot of tags, so rather than "more"'ing over 3 pages of tag information, the log information is presented without tags at all. `-R' Print only the name of the RCS file. `-rREVISIONS' Print information about revisions given in the comma-separated list REVISIONS of revisions and ranges. The following table explains the available range formats: `REV1:REV2' Revisions REV1 to REV2 (which must be on the same branch). `REV1::REV2' Revisions between, but not including, REV1 and REV2. `:REV' Revisions from the beginning of the branch up to and including REV. `::REV' Revisions from the beginning of the branch up to, but not including, REV. `REV:' Revisions starting with REV to the end of the branch containing REV. `REV:' Revisions starting just after REV to the end of the branch containing REV. `BRANCH' An argument that is a branch means all revisions on that branch. `BRANCH1:BRANCH2' `BRANCH1::BRANCH2' A range of branches means all revisions on the branches in that range. `BRANCH.' The latest revision in BRANCH. A bare `-r' with no revisions means the latest revision on the default branch, normally the trunk. There can be no space between the `-r' option and its argument. `-s STATES' Print information about revisions whose state attributes match one of the states given in the comma-separated list STATES. `-t' Print the same as `-h', plus the descriptive text. `-wLOGINS' Print information about revisions checked in by users with login names appearing in the comma-separated list LOGINS. If LOGINS is omitted, the user's login is assumed. There can be no space between the `-w' option and its argument. `log' prints the intersection of the revisions selected with the options `-d', `-s', and `-w', intersected with the union of the revisions selected by `-b' and `-r'. File: cvs.info, Node: log examples, Prev: log options, Up: log log examples ------------ Contributed examples are gratefully accepted. File: cvs.info, Node: rdiff, Next: release, Prev: log, Up: CVS commands rdiff--'patch' format diffs between releases ============================================ * rdiff [-flags] [-V vn] [-r t|-D d [-r t2|-D d2]] modules... * Requires: repository. * Changes: nothing. * Synonym: patch Builds a Larry Wall format patch(1) file between two releases, that can be fed directly into the `patch' program to bring an old release up-to-date with the new release. (This is one of the few CVS commands that operates directly from the repository, and doesn't require a prior checkout.) The diff output is sent to the standard output device. You can specify (using the standard `-r' and `-D' options) any combination of one or two revisions or dates. If only one revision or date is specified, the patch file reflects differences between that revision or date and the current head revisions in the RCS file. Note that if the software release affected is contained in more than one directory, then it may be necessary to specify the `-p' option to the `patch' command when patching the old sources, so that `patch' is able to find the files that are located in other directories. * Menu: * rdiff options:: rdiff options * rdiff examples:: rdiff examples File: cvs.info, Node: rdiff options, Next: rdiff examples, Up: rdiff rdiff options ------------- These standard options are supported by `rdiff' (*note Common options::, for a complete description of them): `-D DATE' Use the most recent revision no later than DATE. `-f' If no matching revision is found, retrieve the most recent revision (instead of ignoring the file). `-l' Local; don't descend subdirectories. `-R' Examine directories recursively. This option is on by default. `-r TAG' Use revision TAG. In addition to the above, these options are available: `-c' Use the context diff format. This is the default format. `-s' Create a summary change report instead of a patch. The summary includes information about files that were changed or added between the releases. It is sent to the standard output device. This is useful for finding out, for example, which files have changed between two dates or revisions. `-t' A diff of the top two revisions is sent to the standard output device. This is most useful for seeing what the last change to a file was. `-u' Use the unidiff format for the context diffs. Remember that old versions of the `patch' program can't handle the unidiff format, so if you plan to post this patch to the net you should probably not use `-u'. `-V VN' Expand keywords according to the rules current in RCS version VN (the expansion format changed with RCS version 5). Note that this option is no longer accepted. CVS will always expand keywords the way that RCS version 5 does. File: cvs.info, Node: rdiff examples, Prev: rdiff options, Up: rdiff rdiff examples -------------- Suppose you receive mail from foo@example.net asking for an update from release 1.2 to 1.4 of the tc compiler. You have no such patches on hand, but with CVS that can easily be fixed with a command such as this: $ cvs rdiff -c -r FOO1_2 -r FOO1_4 tc | \ $$ Mail -s 'The patches you asked for' foo@example.net Suppose you have made release 1.3, and forked a branch called `R_1_3fix' for bugfixes. `R_1_3_1' corresponds to release 1.3.1, which was made some time ago. Now, you want to see how much development has been done on the branch. This command can be used: $ cvs patch -s -r R_1_3_1 -r R_1_3fix module-name cvs rdiff: Diffing module-name File ChangeLog,v changed from revision 1.52.2.5 to 1.52.2.6 File foo.c,v changed from revision 1.52.2.3 to 1.52.2.4 File bar.h,v changed from revision 1.29.2.1 to 1.2 File: cvs.info, Node: release, Next: update, Prev: rdiff, Up: CVS commands release--Indicate that a Module is no longer in use =================================================== * release [-d] directories... * Requires: Working directory. * Changes: Working directory, history log. This command is meant to safely cancel the effect of `cvs checkout'. Since CVS doesn't lock files, it isn't strictly necessary to use this command. You can always simply delete your working directory, if you like; but you risk losing changes you may have forgotten, and you leave no trace in the CVS history file (*note history file::) that you've abandoned your checkout. Use `cvs release' to avoid these problems. This command checks that no uncommitted changes are present; that you are executing it from immediately above a CVS working directory; and that the repository recorded for your files is the same as the repository defined in the module database. If all these conditions are true, `cvs release' leaves a record of its execution (attesting to your intentionally abandoning your checkout) in the CVS history log. * Menu: * release options:: release options * release output:: release output * release examples:: release examples File: cvs.info, Node: release options, Next: release output, Up: release release options --------------- The `release' command supports one command option: `-d' Delete your working copy of the file if the release succeeds. If this flag is not given your files will remain in your working directory. *Warning:* The `release' command deletes all directories and files recursively. This has the very serious side-effect that any directory that you have created inside your checked-out sources, and not added to the repository (using the `add' command; *note Adding files::) will be silently deleted--even if it is non-empty! File: cvs.info, Node: release output, Next: release examples, Prev: release options, Up: release release output -------------- Before `release' releases your sources it will print a one-line message for any file that is not up-to-date. *Warning:* Any new directories that you have created, but not added to the CVS directory hierarchy with the `add' command (*note Adding files::) will be silently ignored (and deleted, if `-d' is specified), even if they contain files. `U FILE' `P FILE' There exists a newer revision of this file in the repository, and you have not modified your local copy of the file (`U' and `P' mean the same thing). `A FILE' The file has been added to your private copy of the sources, but has not yet been committed to the repository. If you delete your copy of the sources this file will be lost. `R FILE' The file has been removed from your private copy of the sources, but has not yet been removed from the repository, since you have not yet committed the removal. *Note commit::. `M FILE' The file is modified in your working directory. There might also be a newer revision inside the repository. `? FILE' FILE is in your working directory, but does not correspond to anything in the source repository, and is not in the list of files for CVS to ignore (see the description of the `-I' option, and *note cvsignore::). If you remove your working sources, this file will be lost. File: cvs.info, Node: release examples, Prev: release output, Up: release release examples ---------------- Release the `tc' directory, and delete your local working copy of the files. $ cd .. # You must stand immediately above the # sources when you issue `cvs release'. $ cvs release -d tc You have [0] altered files in this repository.

After you've run checkout to create your private copy of source from the common repository, other developers will continue changing the central source. From time to time, when it is convenient in your development process, you can use the `update' command from within your working directory to reconcile your work with any revisions applied to the source repository since your last checkout or update. * Menu: * update options:: update options * update output:: update output File: cvs.info, Node: update options, Next: update output, Up: update update options -------------- These standard options are available with `update' (*note Common options::, for a complete description of them): `-D date' Use the most recent revision no later than DATE. This option is sticky, and implies `-P'. See *Note Sticky tags::, for more information on sticky tags/dates. `-f' Only useful with the `-D DATE' or `-r TAG' flags. If no matching revision is found, retrieve the most recent revision (instead of ignoring the file). `-k KFLAG' Process keywords according to KFLAG. See *Note Keyword substitution::. This option is sticky; future updates of this file in this working directory will use the same KFLAG. The `status' command can be viewed to see the sticky options. See *Note Invoking CVS::, for more information on the `status' command. `-l' Local; run only in current working directory. *Note Recursive behavior::. `-P' Prune empty directories. See *Note Moving directories::. `-p' Pipe files to the standard output. `-R' Update directories recursively (default). *Note Recursive behavior::. `-r rev' Retrieve revision/tag REV. This option is sticky, and implies `-P'. See *Note Sticky tags::, for more information on sticky tags/dates. These special options are also available with `update'. `-A' Reset any sticky tags, dates, or `-k' options. See *Note Sticky tags::, for more information on sticky tags/dates. `-C' Overwrite locally modified files with clean copies from the repository (the modified file is saved in `.#FILE.REVISION', however). `-d' Create any directories that exist in the repository if they're missing from the working directory. Normally, `update' acts only on directories and files that were already enrolled in your working directory. This is useful for updating directories that were created in the repository since the initial checkout; but it has an unfortunate side effect. If you deliberately avoided certain directories in the repository when you created your working directory (either through use of a module name or by listing explicitly the files and directories you wanted on the command line), then updating with `-d' will create those directories, which may not be what you want. `-I NAME' Ignore files whose names match NAME (in your working directory) during the update. You can specify `-I' more than once on the command line to specify several files to ignore. Use `-I !' to avoid ignoring any files at all. *Note cvsignore::, for other ways to make CVS ignore some files. `-WSPEC' Specify file names that should be filtered during update. You can use this option repeatedly. SPEC can be a file name pattern of the same type that you can specify in the `.cvswrappers' file. *Note Wrappers::. `-jREVISION' With two `-j' options, merge changes from the revision specified with the first `-j' option to the revision specified with the second `j' option, into the working directory. With one `-j' option, merge changes from the ancestor revision to the revision specified with the `-j' option, into the working directory. The ancestor revision is the common ancestor of the revision which the working directory is based on, and the revision specified in the `-j' option. Note that using a single `-j TAGNAME' option rather than `-j BRANCHNAME' to merge changes from a branch will often not remove files which were removed on the branch. *Note Merging adds and removals::, for more. In addition, each `-j' option can contain an optional date specification which, when used with branches, can limit the chosen revision to one within a specific date. An optional date is specified by adding a colon (:) to the tag: `-jSYMBOLIC_TAG:DATE_SPECIFIER'. *Note Branching and merging::. File: cvs.info, Node: update output, Prev: update options, Up: update update output ------------- `update' and `checkout' keep you informed of their progress by printing a line for each file, preceded by one character indicating the status of the file: `U FILE' The file was brought up to date with respect to the repository. This is done for any file that exists in the repository but not in your source, and for files that you haven't changed but are not the most recent versions available in the repository. `P FILE' Like `U', but the CVS server sends a patch instead of an entire file. These two things accomplish the same thing. `A FILE' The file has been added to your private copy of the sources, and will be added to the source repository when you run `commit' on the file. This is a reminder to you that the file needs to be committed. `R FILE' The file has been removed from your private copy of the sources, and will be removed from the source repository when you run `commit' on the file. This is a reminder to you that the file needs to be committed. `M FILE' The file is modified in your working directory. `M' can indicate one of two states for a file you're working on: either there were no modifications to the same file in the repository, so that your file remains as you last saw it; or there were modifications in the repository as well as in your copy, but they were merged successfully, without conflict, in your working directory. CVS will print some messages if it merges your work, and a backup copy of your working file (as it looked before you ran `update') will be made. The exact name of that file is printed while `update' runs. `C FILE' A conflict was detected while trying to merge your changes to FILE with changes from the source repository. FILE (the copy in your working directory) is now the result of attempting to merge the two revisions; an unmodified copy of your file is also in your working directory, with the name `.#FILE.REVISION' where REVISION is the revision that your modified file started from. Resolve the conflict as described in *Note Conflicts example::. (Note that some systems automatically purge files that begin with `.#' if they have not been accessed for a few days. If you intend to keep a copy of your original file, it is a very good idea to rename it.) Under VMS, the file name starts with `__' rather than `.#'. `? FILE' FILE is in your working directory, but does not correspond to anything in the source repository, and is not in the list of files for CVS to ignore (see the description of the `-I' option, and *note cvsignore::).
