- NAME
- unsit - extract/list files in a Macintosh Stuffit archive
- file
-
- SYNOPSIS
- unsit [ -dflmqruv ] file
-
- DESCRIPTION
- For the Stuffit archive file listed, unsit extracts the
- files in the archive into separate files. This makes it
- possible, for example, to separate a large StuffIt file into
- component files for selective downloading, rather than down-
- loading the larger archive file just to extract a single,
- small file. It also allows the use of StuffIt to compress a
- group of files into a single, smaller archive that can be
- uploaded to a Unix system for storage, printing, etc.
-
- In the normal mode, both the data and the resource forks of
- the component Macintosh files in the archive are extracted
- and stored in Unix files with the extension .data and .rsrc
- appended to the end of the Macintosh file name. In addi-
- tion, a .info file will be created with the Finder informa-
- tion. These three file are compatible with the macput pro-
- gram for downloading to a Mac running Macterminal. If only
- the data or resource fork is extracted, no addition exten-
- sion is appended to the Mac file name. Characters in the
- Mac file name that are illegal (or unwieldy, like spaces)
- are changed to underscores in the Unix file name. The true
- Mac file name is retained in the .info file and is restored
- when the file is downloaded.
-
- StuffIt version 1.5 has the ability to archive a group of
- files and folders in such a way that the hierarchical rela-
- tionship of the files and folders is maintained. Unsit ver-
- sion 1.5 can unpack files archived in this manner and place
- them in corresponding subdirectories so as to maintain the
- hierarchy. As an option, the hierarcy can be flattened out
- and all the files stored in the current directory.
-
- The options are similar to those for macput and unpit.
-
- -f For StuffIt files containing a "Hierarchy Maintained
- Folder" entry, extract the files into a "flat" organi-
- zation (all in the current directory) rather than main-
- taining the hierarchy by creating new directories, etc.
- Default is to maintain the hierarchical folder organi-
- zation.
-
- -l List the files in the archive but do not extract them.
- The name, size, type, and creator of each file is
- listed.

-
-
- -m Assumes the input file in MacBinary format rather than
- macput/macget format and skips over the MacBinary
- header.
-
- -r Extract resources forks only.
-
- -d Extract data forks only.
-
- -u Extract data fork and change into a Unix text file.
- This only works if the file is really a text file.
-
- -q Query user before extracting files and folders. If a
- "n" answer is given for a folder, none of the files or
- folders in that folder will be extracted.
-
- -v Verbose option. Causes unsit to list name, size, type,
- and creator of each file extracted.
-
- BUGS
- Files that were compressed by StuffIt with the Lempel-Ziv
- method and are extracted with the -u switch (text files) are
- not checked for a correct CRC value when unsit uncompresses
- them. This is because unsit pipes the data through compress
- and tr to extract the file and never has a chance to do the
- CRC check.
-
- The compress program has been observed to go into strange
- states when uncompressing a damaged file. Often it will get
- stuck writing out bogus data until the disk fills up. Since
- unsit sends data through compress, the same problem could
- occur when extracting files from a damaged Stuffit archive.
-
- FILES
- For archives that have been compressed with the Lempel-Ziv
- method, the compress program must be present on the system
- and in the search path since unsit uses it for the
- uncompressing. Compress is available from the
- comp.sources.unix archives.
