Running that command from a root konsole works fine, so I set it to run as a cron job every Wednesday.

I'm guessing that it would be safe enough to delete everything dated previous to the last bootup. Am I right?The most logical question is, what is /tmp filling up with? I can't say that in a normally operating system I've seen /tmp filling up "rapidly" without a cause and I'm not the one to go willy-nilly deleting things without known why they are being created.Duh! I mis-read the logfile line. It's not really filling up, though there are things that I think should be deleted.Anne, I run the following command in a cron job: tmpwatch --mtime --verbose --verbose 168 /tmp You may not want the --verbose, and check the manpage for the --mtime option, but basically this deletes all files in /tmp that have not been modified for 168 hours or more./bin/sh: tmpwatch: command not found What could be wonrg?
tmpwatch is /usr/sbin/tmpwatch. Is /usr/sbin in your path in the cronjob?
AnneI personally prefer to use tmpfs in /etc/fstab : tmpfs /tmp tmpfs nosuid,noexec,size=256m,mode=1777 0 0That way /tmp does not use any physical disk space - and is wiped every time I reboot.size=256m is optional - w/o it though, it can use up to half of your physical ram. A 256m /tmp is more than plenty.The only drawback - if you download files larger than the available space in the /tmp filesystem via firefox - the download will fail because firefox assembles it in /tmp. You can change that in Firefox preferences - but I prefer to grab large files via wget rather than firefox download manager.With a 256 MB /tmp - I rarely use more than 1% of it.With /tmp in memory - the disk arm doesn't have to move to write/read temp files, they are read out of memory.
