shar - shell archiver
shar file ...
shar *.c >s # Collect C programs in shell archive
sh <s # Extract files from a shell archive
The named files are collected together into a shell archive written onto
standard output. The individual files can be extracted by redirecting
the shell archive into the shell. The advantage of shar over ar is that
shar archives can be read on almost any UNIX system, whereas numerous,
incompatible versions of ar are in widespread use. Extracting the files
from a shell archive requires that sed be accessible.
