To check account properties you use the command lsuser and specify what property you want to see.
Checking if an account is locked
root@aix:/ # lsuser -a account_locked emerson
emerson account_locked=false
To calculate when was the last time an user logged in to the server, you will need to convert the time displayed. Use the command below to convert.
root@aix:/ # lsuser -a time_last_login emerson
emerson time_last_login=1279036180root@aix:/ # perl -we ‘print(my $time = localtime 1279036180, “\n”)’
