In Unix, how often are the /tmp and /scr directories purged (erased)?

On many Unix systems, the /tmp directory is purged each time the computer is rebooted, or whenever the system administrator feels it is necessary (i.e., when it becomes full). Many systems that have a /scr directory will have a policy dictating how frequently files are removed. Check with your system administrator for information about your system's policy.

For information about scratch space on Indiana University's research systems, see At IU, how much disk space is available to me on the research systems?

Note: In cases where the file system becomes full, more recently accessed files in the /scr directory may be purged to create room.

While anyone can create and use files in the /tmp directory, your /scr/username directory is yours, and cannot be viewed by other users unless you specify otherwise.

At Indiana University, for personal or departmental Linux or Unix systems support, see At IU, how do I get support for Linux or Unix?
