According to the Filesystem Hierarchy Standard:

"The /tmp directory must be made available for programs taht require temporary files.

"Programs must not assume that any files or directories in /tmp are preserved between invocations of the program."

I think that you can actually set things up such that /tmp is cleared when you boot up, but I'm not sure how. When I used to use Mandrake that was an option when setting up the bootloader.

I don't think I'd clear it out without good reason, partiularly with a lot of programs running, but I don't think it'd do any permanent damage.

Why do you want to clear out /tmp anyway? Is it filling up?

Two suggestions:

  1. Delete all the contents of /tmp and then immediately reboot. This is the easy way out.
  2. Shut down all necessary programs and daemons and then delete the contents of /tmp


Either way, you won't fry your system just by deleting the contents of /tmp. Even with option #2, the worst that happens is you have a daemon or two that won't function correctly until you restart them.

If you're running this system as a multi-user server, especially a web server (and especially one that uses PHP) then I'd choose option #1 just to be safe. PHP writes session information to /tmp by default.

I don't know how smart this is, but I've got a gig of ram and 200 MB of swap if that overfills, so I just mount /tmp as tmpfs - little to no footprint while not in use, but it can expand. Since I reboot fairly often on this computer (it is a desktop and I do need to sleep at night), it keeps itself relatively clean. I have especailly liked storing my browser cache files in /tmp - no more damn cookies!

Plenty of people do this and it can actually make some apps that rely heavily on /tmp much faster since they're reading/writing to RAM rather than a hard drive.

So, if you've got the RAM to burn, it can be a great choice.
