How can I see all the members of a group in Linux?

Use the commands:
getent group groupname
or
getent group groupname | awk -F: '{print $4}' | tr "," " "

1So to add group, add user to group, change permissions of folder to group, and get all members of group, you would run the following commands respectively: addgroup programmers adduser donato programmers chown -R root:programmers idea-IU-141.1010.3 getent group programmers– DonatoJun 9, 2015 at 4:56

Interesting find, "getent groups" (without any group specified) and "cat /etc/group" both give exactly the same output, at least on my system.– okolnostOct 4, 2016 at 22:43

I am not sure this works well for non-standard accounts. Try the following two examples:
groups root && getent group root
andgroups lxd && getent group users
. Can anybody shed some light why in above cases root user is not listed as a member of a root group as well as lxd user (you need to have LXD/LXC installed) is not listed as a member of a users group where in fact both have groups assigned to them in groups? Howevergroups pulse && getent group audio
works as expected and pulse user listed as a member of an audio group in both command outputs.– igorSep 17, 2023 at 14:15
You can do
members YOUR_GROUP_NAME
and it will list all the users in the group YOUR_GROUP_NAME
.
If it's not installed by default:
sudo apt-get install members
-
1
-
10

One more way to check all the members of a group is by checking the /etc/group
file which lists all the groups and its members
Example:
root:x:0:
daemon:x:1:
bin:x:2:
sys:x:3:
adm:x:4:syslog,nikhil
tty:x:5:
disk:x:6:
lp:x:7:
mail:x:8:
news:x:9:
uucp:x:10:
man:x:12:
proxy:x:13:
kmem:x:15:
dialout:x:20:
fax:x:21:
voice:x:22:
cdrom:x:24:nikhil
floppy:x:25:
tape:x:26:
sudo:x:27:nikhil
audio:x:29:pulse
The first string (separated by :) specifies the group name and the last string specifies the user added to this group.
