NAME
unshar - unpack a shar file
SYNOPSIS
unshar [ -d directory ] [ -c ] [ -e | -E exit_line ] [
file ... ]
DESCRIPTION
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 man-
ual page reflects unshar version 4.0.
OPTIONS
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 imme-
diately 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 some-
times 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.
