"shar" is not part of standard Unix, it's just a utility people
pass around.  There are at least a dozen variations.

Here's the one I use 90% of the time:  It doesn't do any of the
fancy stuff like compressing binary files or building multi-part
archives, but it works for just packing a bunch of files.  It's
main advantage is that it's a short shell script rather than a
C program.


#! /bin/sh
#	shar <source1> <source2> ... <sourceN> [ > destination ]

echo "#! /bin/sh"
echo "# this is a shell archive, meaning:"
echo "# 1. Remove everything above the #! /bin/sh line"
echo "# 2. Save the resulting text in a file."
echo "# 3. Execute the file with /bin/sh to create the files:"
for i in $* ; do
  echo "#	$i"
done
echo "# This archive created: `date` by $USER"
echo "#"
echo "#"
echo 'export PATH; PATH=/bin:$PATH'
echo "#"

for i do
  echo a - $i >&2
  echo ""
  len=`wc -c < $i`
  echo "if test -f $i"
  echo "then"
  echo "echo shar: will not over-write existing file $i"
  echo "else"
  echo "echo shar: extracting '$i', $len characters"
  echo "sed 's/^X//' > $i <<'SHAR_EOF'"
  sed 's/^/X/' $i
  echo "SHAR_EOF"
  echo "len=\`wc -c < $i\`"
  echo "if test \$len != $len ; then"
  echo "echo error: $i was \$len bytes long, should have been $len"
  echo "fi"
  echo "fi # end of overwriting check"
done
echo "exit 0"
