HowTo: Regular cleanup the Tempfolders

July 19th, 2009 by

If you would like to cleanup regularly your System, we presenting the following Steps!

Launch YaST:
Choose Category “System”, then “Editor for /etc/sysconfig Files”.

Then open “System” and after that open “Cron”.

Here you find the following Entrys:

CLEAR_TMP_DIRS_AT_BOOTUP = “no”
Change to: “yes”
That means: enable or disable the Cleanup Function global.
Default: “no” (=off!)

TMP_DIRS_TO_CLEAR = “/tmp”
That you can leave.
That means: First List from Folders, that can be deleted.
Default: /tmp

MAX_DAYS_IN_TMP = 0
Change to: “1″ (=deletes all Files who are older than 24h)
Means: Max. File Lifetime in days. That is for the Files, defined in TMP_DIRS_TO_CLEAR.
Default: 0 (=disabled)

Close the Editor. You see all changes and you can close the Editor.

Close “YAST”
In the next Systemstart cron cleans up your /tmp.

You can define an second List:

LONG_TMP_DIRS_TO_CLEAR = “”
Means: second Folderlist who can be deleted.
Default: “”
Possible Option: “/var/tmp”

MAX_DAYS_IN_LONG_TMP = 0
Means: Max File Lifetime in days, for all Files who are defined in LONG_TMP_DIRS_TO_CLEAR.
Default: 0 (= disabled)
Possible Option: “28″

    Or, if you have enough ram, you can put something like:
    tmpfs /tmp tmpfs auto,size=256M,uid=0,gid=0,mode=1777 0 0

    It’s not right to delete from /var/tmp. According to Filesystem Hierarchy Standard, this directory contains “temporary files to be preserved between reboots”. You should let applications delete their own files from /var/tmp or you can delete manually if you are sure.
