# of users in linux

kapilbajpai88 · 10-10-2008, 11:41 AM

Hi all,
could anybody tell me how to check the number of users on a linux(RHEL5), as well as the brief statistics of every user.

Thank you in advance,
Kapil Bajpai.

Use the who command. See:

man who

You might type "w"
man w

hi all,

thank you for your precious advice....

but what i wish to know is that whether we have any such measure/command to see all users on a linux machine, like we can see the current active user with 'man' or 'w' command.

Thank you
Kapil Bajpai.

Hi All,

Even Who -q shows only the current active user. I am interested in similar information off all the user in the same machine. For instance, I have 4 users on my RHEL5 machine, and i wish to know their brief statistics like 'w' command gives for the active user only.
I think i am clear now....

Thank you,
Kapil Bajpai.

READ the output of

Code:

su - ( or sudo)
who --help
 --and --
man who

Quote:

~]# who --help
Usage: who [OPTION]... [ FILE | ARG1 ARG2 ]

-a, --all same as -b -d --login -p -r -t -T -u
-b, --boot time of last system boot
-d, --dead print dead processes
-H, --heading print line of column headings
-l, --login print system login processes
--lookup attempt to canonicalize hostnames via DNS
-m only hostname and user associated with stdin
-p, --process print active processes spawned by init
-q, --count all login names and number of users logged on
-r, --runlevel print current runlevel
-s, --short print only name, line, and time (default)
-t, --time print last system clock change
-T, -w, --mesg add user's message status as +, - or ?
-u, --users list users logged in
--message same as -T
--writable same as -T
--help display this help and exit
--version output version information and exit

If FILE is not specified, use /var/run/utmp. /var/log/wtmp as FILE is common.
If ARG1 ARG2 given, -m presumed: `am i' or `mom likes' are usual.

The commmands "w", "who" and "users" all deal with current users as opposed to "All".
if you do "ls /home" you should see a list of all users on the system.
Just did "apropos user" and found a Command "users-admin" that might help.

john test · 10-11-2008, 10:44 AM

Yea "users-admin" gets it. Doesn't show current activity like "W" but shows info on real name etc - allows creation deletion and modification of user accounts

kapilbajpai88 · 10-12-2008, 10:30 AM

You're welcome. Good luck with it!

dasy2k1 · 10-12-2008, 06:48 PM

cat /ect/passwd will also print an ENTIRE list of users..... this includes all the deamon ones and things like nobody

kapilbajpai88 · 10-15-2008, 07:49 AM

Hi There,
your advice worked, now i can see all users and will try to get their details as well.

I have another query, and i hope you can help me.."How can i copy a file from a windows machine into the RHEL5 machine?

Thank You in advance,
Kapil.

>> "How can i copy a file from a windows machine into the RHEL5 machine?

install putty on the windows box, and use "psftp"
or you can install ftp (yum install vsftpd; service vsftpd start) on the linux box, and from windows box, do ftp.

chrism01 · 10-15-2008, 08:04 PM

pscp is easier
