Temporary files: RAM or disk?Temporary files: RAM or disk?Posted Jun 5, 2012 15:40 UTC (Tue) by nybble41 (subscriber, #55106)In reply to: Temporary files: RAM or disk? by roblucid Parent article: Temporary files: RAM or disk?

The distinction which I learned, which may very well be non-universal, was that /tmp is for temporary files which are tied to a particular process. These files can be removed as soon as the process exits, including on reboot. The /var/tmp directory is for temporary files which may need to outlast a given process, possibly across reboots, and should thus be cleared out much more sparingly based on the ages of the files.
Of course, not all processes follow this distinction.
