The files in /tmp are created by samba if you have a lpq cache time
(they may also be created if you don't, but I don't think so) in order
to cache the lpq information when they are queried by a client (I have
no idea why they are left hanging around forever by default by samba,
but they are). You can put the following line into a cron job in order
to delete any files that match lpq.* in the toplevel of the /tmp
directory that are over a day old (the insanity of the find command is
to prevent it from going below the top level of the /tmp directory to
any subdirectories - I know, if it is in /tmp is should be considered
pretty much OK to delete at any time, but I'm just this crazy and
paranoid - besides, I wanted to figure out one day how to get find to do
that):
find /tmp \( \! \( -type f -o -name 'tmp' \) -o -name 'lpq.*' \) -prune
-a -name 'lpq.*' -mtime +1 -exec rm {} \;
I have no idea why the tempXXXX files are hanging around in your spool
directory. Could this have something to do with the new lpq caching in
LPRng?
