here too. But I can't seem to find a date for shar.
I'm under the impression that shar came later in the 1980s. Google's
archive for net.sources only goes back to 1987 (unless I'm doing it
wrong) and clearly shar was already well established by then.
Can anyone put a date on shar, or at least before/after 6/1/1980?
Thanks!

ISTR that there was a shar-style program in Kernighan & Pike's "The
UNIX Programming Environment". That was circa 1984 but shar had been
around for a while before that. Writing a simple shar creator
in shell was pretty trivial:
for i in "$@"
do
echo echo ---- Extracting $i ----
echo "cat << 'EOF' > $i"
cat $i
echo EOF
done > file.shar
And I think many people just did that sort of thing on the fly
at first.
Over time shar creators got fancier, with the ability to make directories,
uuencode binaries, and split large files and put them back together
again. (Cf. the kind of postings in the netnews *.sources groups.)
Not sure this helps to put a date on shar, but certainly shar archives
were widely used in the 1983-1985 time frame...
