Log File Confusion???

[jkc924]

Can any/all .log files be removed when large or are there some that cannot? How do I know which ones I can remove that will be automatically recreated, which ones I can remove and need to touch to recreate, and are there any .log files that have to remain intact that can never be removed...
Any advise will be greatly appreciated.. I cannot find any information in any documentation about cleanup of log files or for that matter, any other unneeded files taking up space.

Thanks,

Judy

In cron there is a skulker script which you can look at which will cleanup logs. Also the following can be observerd:

/tmp, /var/tmp, /var/preserve - delete older than 7 days.
/var/spool/mqueue - delete older than 7 days.
/var/spool/mail - delete any not modified for 14 days.
/var/spool/qdaemon, /usr/lib/lpd/qdir - delete any file older than 7 days.
/var/lp/logs - delete any file older than 7 days.
core and snapcore - delete after 2 days.
nohup.out - delete after 2 days.
.xerrors - truncate.
mbox- truncate.
smit.log and smit.script - keep .5MB of root; last 1000 lines of others.
/var/adm/wtmp - keep min of 60 days; truncate rest.
/etc/security/failedlogin - keep min of 60 days; truncate rest.
/var/adm/sulog - keep min of 60 days; delete the rest.
/var/adm/cron/log - truncate; keep last 10 lines.
/var/tmp/snmp.log - truncate; keep last 100 lines.
/var/tmp/dpid.log, /var/tmp/dpid2.log, /var/tmp/hostmidb.log, /var/tmp/muxatmd - truncate; keep last 100 lines.
dead.letter - delete.
trcfile - keep 2 days then delete.

If in doubt just zero it (truncate) '> logfile'
