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.
