Name
unshar
Synopsis
unshar [options] [files]Unpack a shell archive (shar file). unshar scans mail messages looking for the start of a shell archive. It then passes the archive through a copy of the shell to unpack it. unshar accepts multiple files. If no files are given, standard input is used.
Options
- -c, --overwrite
Overwrite existing files.
- -d directory, --directory=directory
Change to directory before unpacking any files.
- -e, --exit-0
Sequentially unpack multiple archives stored in same file. This uses the clue that many shar files are terminated by an exit 0 at the beginning of a line. (Equivalent to -E “exit 0“.)
- -E string, --split-at=string
Like -e, but allows you to specify the string that separates archives.
- -f, --force
Same as -c.
- --help
Print help message and then exit.
- --version
Print the version number and then exit.
