  1. Best Answer

    List all users with a /home folder:

    awk -F: '/\/home/ {printf "%s:%s\n",$1,$3}' /etc/passwd

    or all users with a UID >= 1000:

    awk -F: '($3 >= 1000) {printf "%s:%s\n",$1,$3}' /etc/passwd

    a combination

    awk -F: '/\/home/ && ($3 >= 1000) {printf "%s:%s\n",$1,$3}' /etc/passwd

    or for all entries

    awk -F: '{printf "%s:%s\n",$1,$3}' /etc/passwd

  2. You can find it easily by just using cut :

    cut -d: -f1,3 /etc/passwd

    • -d: sets the delimiter as : for cut

    • -f1,3 extracts the field 1 and 3 only delimited by : from the /etc/passwd file

    Check man cut to get more idea.

    Example :

    $ cut -d: -f1,3 /etc/passwd
root:0
daemon:1
bin:2
sys:3
sync:4
games:5
......

    If you have ldap configured, to include the ldap users in the output :

    getent passwd | cut -d: -f1,3

  3. Alternatively to list all users including UID and GID information.

    for user in $(cat /etc/passwd | cut -f1 -d":"); do id $user; done

  4. Because you are trying to list the UID and Username, the below command works better best on Solaris. They have two awk

    awk -F: '($3 >=1000) {printf "%s:%s",$1,$3}' /etc/passwd

  5. I find the easiest way is to have webmin on your server and simply go to System > Users and Groups and there you have a nicely formatted list with all usernames & groups with their uid's, home directory etc.
