How to select last 7 days entry from SULOG or LAST command

Hi All,

I need to get last 7 days log entries from sulog. The same has to be done for the last command.

for ex: when i search for a user "abc" in sulog, i only want to check his entries for the last 1 week.

The same has to be done for last command.

Can anyone suggest some tips.

Thanks in Advance

Regards
