Hi all,
We seem to have a csh curiosity here. As documented in the
man pages for csh, if one has a shell script which contains
the << inline input redirection, a temporary file is created
in /tmp containing the inline data, but this file is not
removed when the script completes.
e.g.:
#!/bin/csh -f
#
cat - <<eot
123
456
789
eot
This leaves a file in /tmp with a random name starting with sh
This doesnt happen with tcsh, nor with csh/tcsh on a Linux box.
(Maybe the file is never created, or maybe it's deleted before
I get a chance to see it). It's normally not a problem, (in fact
we only discovered it when /tmp filled up for other reasons),
since there is a cron job which deletes unused /tmp files unaccessed
for a few days, but we occasionally have a burst of jobs using
the << input, which could generate hundreds of thousands of such
files.
Is this a bug or a feature I wonder...
Happy New Year,
Terry.
