       unshar - unpack a shar file


       unshar [ options ] [ 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.


       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.

              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 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.

       -f  --force
              The same as -c.

       The shar and unshar programs  is  the  collective  work  of  many  authors.   Many  people
       contributed  by  reporting  problems, suggesting various improvements or submitting actual
       code.  A list of these people is in the THANKS file in the sharutils distribution.
