i need to know how long a user has been logged on the system...

[Bob_16]

what command will tell me how long a user has been logged on the system? it doesn't matter if they are doing anything, just logged in and just sitting at a prompt $.

thanks

Hello,

probably the easiest way is to run:

who -a

Take care, Steffi Jones

Hi,

I just thought about another option for you.

lastb

That will show you too when a user logged in.
Whatever works best for you :-)

Hi,

Steffi's ideas are great but she probably meant to say last and not lastb. The lastb command shows "bad" logins while last shows all previous and current logins.
