Re: Scheme shellscripts

[agate!eris!mwm@labrea.stanford.edu (Mike (I'm in love with my car) Meyer)]

In article <various@many.sites> many people write shell scripts with
lines like:

	echo > .tmp '(set! $* (quote ('$*')))'

in them. This has one nasty problem - try doing "cd /; <scheme-program>".
You'll find (well, you ought to find) that it dies - you can't create
the scratch file you want. Of course, if two people are in the
directory you're running in and running that command, you'll have
probles too.

Instead, try doing:

	echo > /tmp/runscheme.$$ '(set! $* (quote ('$*')))'

This creates a file in /tmp with the process id of the shell executing
the script in it's name. That solves both problems at once.
