System messages
About this task
The
/var/log
directory contains the message files. The most recent messages are in
/var/log/
messages
. The system consolidates older system messages into weekly message files. You can
identify these message files by the date of the message files. The message files also contain crash
reports and other data that might increase the hard disk usage. Delete all unnecessary message
files in the
/var/log
directory to prevent excess hard disk usage. You can automate this task by
using the
crontab
utility. For more information about
crontab
, see your Linux
®
system
documentation.
