Solaris managing users - Gathering more information
Now I am learning user administration under Solaris. Here is what so far I had learned. Solaris use /etc/passwd, /etc/group and /etc/shadow file to store user names and password information. I have also noticed that /etc/oshadow file, which is a temporary file used by passwd, passmgmt and pwconv to update the real shadow file.
To print all system account you need to use awk command:
$ awk -F: awk -F: ' $3 ≤ 99 { print $0 }' /etc/passwd
OR to just display list of all regular user:
$ awk -F: ' $3 > 99 { print $0 }' /etc/passwd
- IDs 0-99 are for Solaris system accounts
- IDs 100-999 for applications
- IDs 1000-60000 for normal users
Solaris also support id command to list user UID and GID:
$ id
uid=1000(rock) gid=1(other)
To list user name, user ID and all the groups to which the user belongs you need to pass -a option to id command:
$ id -a
uid=1000(rock) gid=1(other) groups=1(other), 3(sys),4(adm), 100(wwwftp)
List user and system login information:
This command displays information on user and system logins known to the system.
# logins
Getting more information about users
Find out who is on the system
$ who
Display information about currently logged-in users and what they are doing
$ w
Find out who is doing what (just like w command)
$ whodo
Dispaly user's login name:
$ logname
$ echo $LOGNAME
Try out who command (fun):
$ who am i
$ who r u
$ who 1 2
$ who we are
$ who the hell you are
Find out shell you are using:
