.TH UNSHAR 1 "August 12, 1990"
.SH NAME
unshar \- unpack a shar file
.SH SYNOPSIS
unshar [ \f2\-d\f1 directory ] [ \f2\-c\f1 ] [ \f2\-e\f1 | \f2\-E\f1 exit_line ] [ file ... ]
.SH DESCRIPTION
.PP
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.
.PP
The \f2\-d\f1 option tells unshar to change directory before unpacking
any files.
.PP
The \f2\-c\f1 option is passed through to 'sh' as a parameter to the unpacked
script.  Many archive shar scripts (including those produced by
shar 3.40 and newer)
use this to indicate that existing files should be overwritten.
.PP
Unshar can unpack shar files that are concatenated in one file with the
\f2\-e\f1 option, which separates files by recognizing the "exit 0" string
at the beginning of a line. 
The \f2\-E\f1 option allows you to specify the string that separates archives
if "exit 0" isn't appropriate. (Hint: most .signatures have a "\-\-" on a line
right before them). \f2\-e\f1 is equivalent to \f2\-E "exit 0"\f1.
