Systems clean the /tmp directory using various methods, which can include:
-
Startup Scripts: During system boot, startup scripts (like those in
/etc/init.dor systemd services) may include commands to delete all files in/tmp. -
Cron Jobs: Scheduled tasks (cron jobs) can be set up to periodically clean up old files in
/tmp. For example, a cron job might run daily to delete files that haven't been accessed in a specified number of days. -
Systemd Temporary File Cleanup: On systems using systemd, the
tmpfiles.dconfiguration can specify rules for cleaning up/tmp. This can include settings for automatic deletion based on file age. -
Manual Cleanup: Administrators can manually clean
/tmpusing commands likerm -rf /tmp/*to remove all files, though this is typically done with caution. -
File System Features: Some file systems have built-in features that automatically manage temporary files, including cleanup policies.
