/tmp and /var/tmp

/tmp
If /tmp is restarted, the file will be completely lost.

→ /tmp should always be available to programs that require temporary files.
The program should not assume that the file or directory remains in /tmp at the next boot.

/var/tmp
/var/tmp does not disappear after rebooting, but sometimes the file may disapper.

あれ、全然使われ方が違う！？

/var/tmp is used by programs that require temporary files and directories, and will not be deleted when the system is restarted. Therefore, the data of /var/tmp is held longer than the data of /tmp.
Files and directories placed in /var/tmp should not be deleted at system restart. Normally, data in /var/tmp is deleted by site-specific rules, but basically it is desirable to delete less frequently than /tmp.
