- NAME
- ci - check in RCS revisions
-
- SYNOPSIS
- ci [ options ] file ...
-
- DESCRIPTION
- Ci stores new revisions into RCS files. Each file name end-
- ing in `,v' is taken to be an RCS file, all others are
- assumed to be working files containing new revisions. Ci
- deposits the contents of each working file into the
- corresponding RCS file. If only a working file is given, ci
- tries to find the corresponding RCS file in the directory
- ./RCS and then in the current directory. For more details,
- see the file naming section below.
-
- For ci to work, the caller's login must be on the access
- list, except if the access list is empty or the caller is
- the superuser or the owner of the file. To append a new
- revision to an existing branch, the tip revision on that
- branch must be locked by the caller. Otherwise, only a new
- branch can be created. This restriction is not enforced for
- the owner of the file, unless locking is set to strict (see
- rcs(1L)). A lock held by someone else may be broken with
- the rcs command.
-
- Normally, ci checks whether the revision to be deposited is
- different from the preceding one. If it is not different, ci
- either aborts the deposit (if -q is given) or asks whether
- to abort (if -q is omitted). A deposit can be forced with
- the -f option.
-
- For each revision deposited, ci prompts for a log message.
- The log message should summarize the change and must be ter-
- minated with a line containing a single `.' or a control-D.
- If several files are checked in, ci asks whether to reuse
- the previous log message. If the standard input is not a
- terminal, ci suppresses the prompt and uses the same log
- message for all files. See also -m.
-
- The number of the deposited revision can be given by any of
- the options -r, -f, -k, -l, -u, or -q.
-
- If the RCS file does not exist, ci creates it and deposits
- the contents of the working file as the initial revision
- (default number: 1.1). The access list is initialized to
- empty. Instead of the log message, ci requests descriptive
- text (see -t below).
-
- -r[rev] assigns the revision number rev to the checked-in
- revision, releases the corresponding lock, and
- deletes the working file. This is the default.

-
- Rev may be symbolic, numeric, or mixed.
-
- If rev is a revision number, it must be higher
- than the latest one on the branch to which rev
- belongs, or must start a new branch.
-
- If rev is a branch rather than a revision number,
- the new revision is appended to that branch. The
- level number is obtained by incrementing the tip
- revision number of that branch. If rev indicates
- a non-existing branch, that branch is created with
- the initial revision numbered rev.1.
-
- If rev is omitted, ci tries to derive the new
- revision number from the caller's last lock. If
- the caller has locked the tip revision of a
- branch, the new revision is appended to that
- branch. The new revision number is obtained by
- incrementing the tip revision number. If the
- caller locked a non-tip revision, a new branch is
- started at that revision by incrementing the
- highest branch number at that revision. The
- default initial branch and level numbers are 1.
-
- If rev is omitted and the caller has no lock, but
- he is the owner of the file and locking is not set
- to strict, then the revision is appended to the
- default branch (normally the trunk; see the -b
- option of rcs(1L)).
-
- Exception: On the trunk, revisions can be appended
- to the end, but not inserted.
-
- -f[rev] forces a deposit; the new revision is deposited
- even it is not different from the preceding one.
-
- -k[rev] searches the working file for keyword values to
- determine its revision number, creation date,
- state, and author (see co(1)), and assigns these
- values to the deposited revision, rather than com-
- puting them locally. It also generates a default
- login message noting the login of the caller and
- the actual checkin date. This option is useful
- for software distribution. A revision that is sent
- to several sites should be checked in with the -k
- option at these sites to preserve the original
- number, date, author, and state. The extracted
- keyword values and the default log message may be
- overridden with the options -r, -d, -s, -w, and
- -m.
-
- -l[rev] works like -r, except it performs an additional co

-
-
- -l for the deposited revision. Thus, the deposited
- revision is immediately checked out again and
- locked. This is useful for saving a revision
- although one wants to continue editing it after
- the checkin.
-
- -u[rev] works like -l, except that the deposited revision
- is not locked. This is useful if one wants to
- process (e.g., compile) the revision immediately
- after checkin.
-
- -q[rev] quiet mode; diagnostic output is not printed. A
- revision that is not different from the preceding
- one is not deposited, unless -f is given.
-
- -ddate uses date for the checkin date and time. Date may
- be specified in free format as explained in co(1).
- Useful for lying about the checkin date, and for
- -k if no date is available.
-
- -mmsg uses the string msg as the log message for all
- revisions checked in.
-
- -nname assigns the symbolic name name to the number of
- the checked-in revision. Ci prints an error mes-
- sage if name is already assigned to another
- number.
-
- -Nname same as -n, except that it overrides a previous
- assignment of name.
-
- -sstate sets the state of the checked-in revision to the
- identifier state. The default is Exp.
-
- -t[txtfile]
- writes descriptive text into the RCS file (deletes
- the existing text). If txtfile is omitted, ci
- prompts the user for text supplied from the stan-
- dard input, terminated with a line containing a
- single `.' or control-D. Otherwise, the descrip-
- tive text is copied from the file txtfile. During
- initialization, descriptive text is requested even
- if -t is not given. The prompt is suppressed if
- standard input is not a terminal.
-
- -wlogin uses login for the author field of the deposited
- revision. Useful for lying about the author, and
- for -k if no author is available.
-
- FILE NAMING
- Pairs of RCS files and working files may be specified in 3
- ways (see also the example section of co(1)).

-
- 1) Both the RCS file and the working file are given. The RCS
- file name is of the form path1/workfile,v and the working
- file name is of the form path2/workfile, where path1/ and
- path2/ are (possibly different or empty) paths and workfile
- is a file name.
-
- 2) Only the RCS file is given. Then the working file is
- assumed to be in the current directory and its name is
- derived from the name of the RCS file by removing path1/ and
- the suffix ,v.
-
- 3) Only the working file is given. Then ci looks for an RCS
- file of the form path2/RCS/workfile,v or path2/workfile,v
- (in this order).
-
- If the RCS file is specified without a path in 1) and 2),
- then ci looks for the RCS file first in the directory ./RCS
- and then in the current directory.
-
- FILE MODES
- An RCS file created by ci inherits the read and execute per-
- missions from the working file. If the RCS file exists
- already, ci preserves its read and execute permissions. Ci
- always turns off all write permissions of RCS files.
-
- FILES
- The caller of the command must have read/write permission
- for the directories containing the RCS file and the working
- file, and read permission for the RCS file itself. A number
- of temporary files are created. A semaphore file is created
- in the directory containing the RCS file. Ci always creates
- a new RCS file and unlinks the old one. This strategy makes
- links to RCS files useless.
-
- DIAGNOSTICS
- For each revision, ci prints the RCS file, the working file,
- and the number of both the deposited and the preceding revi-
- sion. The exit status always refers to the last file
- checked in, and is 0 if the operation was successful, 1 oth-
- erwise.
