unshar - unpack a shar file
unshar [ -d directory ] [ -c ] [ -e
| -E exit_line ] [ 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. It will accept multiple files. If no files are
given, standard input is used. This manual page reflects unshar version
4.0.
Options have a one letter version starting with - or a long version
starting with --. The exception is --help and --version which does not have a
short version.
- --version
- Print the version number of the program on standard
output, then immediately exits.
- --help
- 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 -c argument to indicate that existing files
should be overwritten.
- -e --exit-0
- This option exists mainly for people who
collect many shell archives into a single mail folder. With this option,
`unshar' isolates each different shell archive from the others which have
been put in the same file, unpacking each in in turn, from the beginning
of the file towards its end. Its proper operation relies 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 the string that separates
archives if `exit 0' isn't appropriate.
For example, noticing that most `.signatures'
have a `--' on a line right before them, one can sometimes use `--split-at=--' for
splitting shell archives which lack the `exit 0' line at end. The signature
will then be skipped altogether with the headers of the following message.
