right in this way

# cat /dev/null > /var/adm/wtmp

Do you care about keeping any recent login stats?

Hi,

There might be other directories like /var/adm/sw, /var/adm/crash which may consume more space than /var/adm/wtmp. You can clear those directories instead of wtmp.

Use this command to check which dir consumed more space

#du -xk /var |sort -nr |head -25

Then you can decide which dir should be cleared off..

Hi:

Do NOT manually munge with anything in '/var/adm/sw' no matter how large it is. To do so will probably render your server un-patchable. Instead, to regain space, do:

# cleanup -c 1

...which removes the rollback copies of patches commited at least once. Usually this returns significant space if you have been routinely patching.

Regardsa!

very simple,
1, backup current log
#tar -cvf /tmp/oldlog.tar /var/adm/wtmp
2, then trim
#>/var/adm/wtmp

That all

Hi,

The best way is

>/var/adm/wtmp

Maximum SA are using this way to trim any file.
