is there a command to see when the last time a user has been online if they arent?
When I use who it shows who is online and from what time they logged in but is there a way I can see the last time someone was logged on if they aren't online? Is it with the who command?
thx

if you want to filter out the last time alone then use:
Code:
last |head -1

Code:
pandeeswaran@ubuntu:~$ last |head -1
pandeesw pts/0        :0               Mon Jan 16 13:13   still logged in

thank you

im writing a script that displays the last time the user has been on and a quick question here

Currently it displays the last time the user has been on but multiple times, will using head -1 limit it to one? I have tried head -1 and it returns nothing in the script

Code:
 last | grep $1 | awk '{print $1 "is not online and last logged in" $5 "" $6 "" $9"" $10}'

the $1 is the input from the user

Try this:
Code:
last $1 |head -1| awk '{print $1 "is not online and last logged in" $5 "" $6 "" $9"" $10}'

Why use grep user when you can give the user name as argument to last?

If you really wants to use grep , then try this:
Code:
last -w|grep $1
