shar: a blast from the past
By jag on Mar 03, 2006
John Gilmore was going through some old backup cartridge tapes. He stumbled on the following email. "shar" was old in 82... I think I actually wrote the script in the email in 78 or 79.
Bits and memes never die.
From decwrl!decvax!microsof!uw-beave!jim Mon Oct 18 11:08:34 1982 Subject: Shell archiver Newsgroups: net.sources I see a lot of sources posted here which consist of several files, all catted together, and then I have to edit the source to extract all the files. Here is a simple shell script which will package up a bunch of files into a "shell archive", which when used as input to a shell, will extract the constituent files (is that perfectly clear?). For example, if I want to distribute a program consisting of files foo1.c, foo2.c, and makefile, I would type "shar archive foo1.c foo2.c makefile" and I would then post "archive" to the net. Recipients would then run the archive into their shell and would get back the original files. Here it is: # shar -- Shell archiver AR=$1 shift for i do echo a - $i echo "echo x - $i" >>$AR echo "cat >$i <<'!Funky!Stuff!'" >>$AR cat $i >>$AR echo "!Funky!Stuff!" >>$AR done Thanks to James Gosling at CMU for this idea.
