unshar - unpack a shar file
unshar [ options ] [ file ... ]
Unshar scans mail messages looking for the start of a shell archive. Itthen passes the archive through a copy of the shell to unpack it. Itwill accept multiple files. If no files are given, standard input is used.
Options have a one letter version starting with - or a long version startingwith --. The exception is --help and --version,which does not have a short version.
- Print the version number of the program on standard output,then immediately exits.
- Print a help summary on standard output, then immediately exits.
- -d DIRECTORY --directory=DIRECTORY
- Change directory to DIRECTORY before unpacking any files.
- -c --overwrite
- Passed as an option to the shar file. Many shell archive scripts(including those produced by `shar' 3.40 and newer) accepts a -cargument to indicate that existing files should be overwritten.
- -e --exit-0
- This option exists mainly for people who collect many shellarchives into a single mail folder. With this option, `unshar'isolates each different shell archive from the others which havebeen put in the same file, unpacking each in turn, from thebeginning of the file towards its end. Its proper operationrelies on the fact that many shar files are terminated by a`exit 0' at the beginning of a line.
Option -e is internally equivalent to -E "exit 0".
- -E STRING --split-at=STRING
- This option works like -e, but it allows you to specify thestring that separates archives if `exit 0' isn't appropriate.
For example, noticing that most `.signatures' have a `--' on aline right before them, one can sometimes use `--split-at=--' forsplitting shell archives which lack the `exit 0' line at end. Thesignature will then be skipped altogether with the headers of thefollowing message.
- -f --force
- The same as -c.
Any message from the shell may be displayed.
The shar and unshar programs is the collective work of many authors.Many people contributed by reporting problems, suggestingvarious improvements or submitting actual code. A list ofthese people is in the THANKS file in the sharutils distribution.
