A while ago I posted my 3b1 ``picture'' program to unix-pc.sources. (If you
didn't get it and are still interested send me a note.) The source code
popens ("zcat pfile"); in order to allow the pictures to live as compressed
data on the disk (huge disk savings).
A number of people don't seem to know about ``zcat''. ``zcat'' is like
``uncompress'', it is just a link to the ``compress'' file. If you look
at the source (it is public domain) you'll see that compress checks
argv[0] to determine if it started as ``compress'', ``uncompress', or
``zcat''. ``ls -il compress uncompress'' should show a link count of at
least two and the same inode number. Just ``ln compress zcat'' and you've
got the zcat program.
I also vaguely remember someone stating that AT&T installs often put a
new compress in place. This was a problem for some reason, but I can't
remember what the real issue was. Hopefully someone will take pity, and
do a follow up to this article (or add the info to commonly asked 3b1
questions).

the ones that i've seen put the compress in the temporary installation
directory; it gets blown away when install exits.
i don't know if this is because:
a) it might trash a compress already installed
or
b) if compress is not already installed, you probably don't have
rights (?) to it.

I compiled the version from the news distribution with the shared library and stripped it. This produced a binary of exactly the same length as the one from the terminfo disk. Les Mikesell
