Number of current sessions for user


Hi!

when I run "su <username>" as root, a new session is created. If wanted to know how many such sessions currently exists for a particular user (active or inactive), how do I find that out?

Thanks in advance,
-Neel.

I found that "who" gives the users that have logged in to terminal. Even if "su <username>" succeeds in changing the owner of the session/effective uid, that does not affect output of "who".

To rephrase the original question, what I want is the way to find out how many sessions exist with effective uid of given user.

Do let me know if I am missing something.

Thanks again,
-Neel.

Hi,

You can use 'users' from the cli which will give you the user name then perform on that.

Quote:
excerpt from 'man users';

users - print the user names of users currently logged in to the cur-
rent host

SYNOPSIS
users [OPTION]... [ FILE ]

DESCRIPTION
Output who is currently logged in according to FILE. If FILE is not
specified, use /var/run/utmp. /var/log/wtmp as FILE is common.

--help display this help and exit

--version
output version information and exit

I hope I understand corectly what you mean by a "session"
in this context

Code:
ps -eo euid,command|grep bash|grep -v grep | sort|uniq -c
