How to find logged in users

A common question is how to find out who is currently logged into the unix/linux server as well as past users who were logged in and then logged out.  Basically, we want to know what is going on with our servers.


 


Find out who currently is logged in you can run a couple of commands.


 


My most used command to find who is currently logged in is:




dhosang@usrn2netweb01:~$ sudo who
rfrick pts/0        2013-12-03 09:22 (10.6.5.224)
pmack    pts/1        2013-12-03 09:51 (10.7.152.26)
dhosang  pts/2        2013-12-03 10:49 (10.60.145.96)

You can also run this to find out who is logged in still




dhosang@usrn2netweb01:~$ last | fgrep "still logged in" | cut -d" " -f1 | uniq -u
dhosang
pmack
rfrick

But let's say you just want to see who has recently logged in and may have already logged out. Well then, run this command




dhosang@usrn2netweb01:~$ last
alawrenc pts/4        10.60.130.51     Tue Dec  3 10:57   still logged in
dhosang  pts/2        10.60.145.96     Tue Dec  3 10:49   still logged in
pmack    pts/1        10.7.152.26      Tue Dec  3 09:51   still logged in
rfrick pts/0        10.6.5.224       Tue Dec  3 09:22   still logged in
pmack    pts/2        10.7.128.40      Mon Dec  2 14:41 - 15:29  (00:47)
psheguns pts/1        10.6.16.22       Mon Dec  2 14:37 - 14:44  (00:06)
psheguns pts/1        10.6.16.22       Mon Dec  2 14:32 - 14:36  (00:04)
psheguns pts/0        10.6.16.22       Mon Dec  2 14:10 - 16:30  (02:19)
bjarrett pts/0        10.6.5.151       Mon Dec  2 08:41 - 08:43  (00:01)
