UNIX for Dummies Questions & Answers

I would like to find out the last time all users have logged in or out. I tried the last command, but it could not find the wtmp file in /var/adm (I searched in othe directories also). This is an AIX rs6000 4.2.1 system. We are moving our applications from this system to an AIX 5.2 system and I would like to not have to create logins for users that are no longer using them. Thank you for any help you can give me.

Try the 'last' command. I am not sure about AIX, I have never worked on it, but it works fine on Sun and HP.

I did try the "last" command, but it did not find the wtmp file in the /var/adm directory. Anyother suggestions?

I found the command lsuser and did this to get a list of users and the last time logged in:
lsuser -a time_last_login ALL > users.txt

Which gives me this result:
username time_last_login=1046099951
username time_last_login=1074022275
username time_last_login=899997008
.
.
username time_last_login=1046099951
username time_last_login=1074022275
username time_last_login=899997008

Is it possible to get the last date logged in from the above?

when you say 'get the last date' what do you exatcly mean?
the 'date' is already there preceeded by '=' - you should be easily be able to use sed/awk to get the value.

That is what I am looking for either sed, awk or any other type of code to get the value.

Code:

echo 'username time_last_login=1046099951' | sed 's/.*=\(.*\)$/\1/'
