Do a man on finger and who

#man finger
#man who

This will give all the options that you can use with these commands

try them:

# finger
# who

finger gives a lot more information, bu can be a security risk so could be disabled on your system. It seraches for files such as .plan, ..forward and .project to supply some
of the personal information

w is another one that you might want to check out

# w

BR

I suppose this will give the info about all users who are currently logged in ->

Users who are not logged in will not be got by these commands

Code:

cat /etc/passwd | awk -F ":" '{print $1}'

gives you all users . However system users i.e, shutdown,apache so on will also be exhibited

Code:

cat /etc/passwd | awk -F ":" '{if($3>=500){print $1}}'

Maybe this will be a bit more near to what you want .
I suppose only "nfsnobody" is the user u don't want
