Linux Show All Group Command Members

I’m a brand new Linux consumer and created a few teams on the server. I want to search out out all members of a bunch referred to as “ftponly”. How do I record all members of a bunch on Linux or Unix-like techniques?

The /and many others/group file is a textual content file that defines the teams on the Linux and Unix primarily based techniques. You’ll be able to merely question this file to search out and record all members of a bunch.

Linux Present All Members of a Group Instructions

  1. /and many others/group file – Consumer group file
  2. members command – Listing members of a bunch
  3. lid command (or libuser-lid on newer Linux distros) – Listing consumer’s teams or group’s customers

There are two varieties of teams in Linux:

  • Main group – is the primary group that’s related to consumer account. Every consumer is a member of precisely one main group.
  • Secondary group – used to offer further rights to consumer. For instance, entry to the dvd/cdrom drive may be granted with assist of cdrom group.

Linux: Listing all members of a bunch utilizing /and many others/group file

Use the grep command as follows:
$ grep ‘grpup-name-here’ /and many others/group
$ grep ‘ftponly’ /and many others/group
$ grep -i –color ‘ftponly’ /and many others/group

ftponly:x:1001:raj,vivek,archana,sai,sayali

To get only a record of all members of a bunch referred to as ftponly, sort the next awk command:

awk -F’:’ ‘/ftponly/{print $4}’ /and many others/group
# record all members of sudo group in linux #
awk -F’:’ ‘/sudo/{print $4}’ /and many others/group

Show group memberships for every Linux consumer

Need to see group memberships for every given USERNAME below Linux? The syntax is as follows for the teams command:
teams
teams {USERNAME}
teams vivek
The next outputs signifies that the consumer named ‘vivek’ is a part of 4 teams together with ‘vivek’ main group:

vivek : vivek wheel lxd vboxusers

Linux Listing all members of a bunch utilizing members command

Warning: members command isn’t put in on most Linux distros. Use yum command or apt-get command/apt command to put in the identical:
$ sudo apt-get set up members

To outputs members of a bunch referred to as ftponly, enter:
$ members {GROUPNAME}
$ members ftponly

On this instance the members command shows a space-separated record of group member names on display.

Easy methods to record all customers in a Linux group utilizing lid command

You’ll be able to shows details about teams containing consumer identify, or customers contained in group identify utilizing lid command as follows.

Warning: lid command isn’t put in on most distros. Use yum command or apt-get command to put in the identical:
$ sudo apt-get set up libuser

To see customers contained in group named ‘ftponly’:

# lid -g ftponly
Please word that newer model of libuser renamed the lid command to libuser-lid. Thus, use it as follows:
$ sudo libuser-lid -g ftponly
Pattern outputs:

raj(uid=1001)
vivek(uid=1002)
archana(uid=1003)
sai(uid=1004)
sayali(uid=1005)

To indicate details about teams containing consumer named ‘nixcraft’:

Use lid command or libuser-lid command on Linux to indicate all members of a bunch named nixcraft:
# lid nixcraft
OR
$ sudo libuser-lid nixcraft
Pattern outputs:

adm(gid=4)
cdrom(gid=24)
sudo(gid=27)
dip(gid=30)
plugdev(gid=46)
lpadmin(gid=109)
nixcraft(gid=1000)
sambashare(gid=124)

See lid command man web page for extra info.

Easy methods to record teams in Linux

To see all customers, run much less command/extra command:
much less /and many others/group
OR
extra /and many others/group
Another choice is to sort the next getent command:
getent group
For instance, find the members of a bunch with the identify vboxusers, run:
getent group vboxusers
Pattern outputs indicating vivek and raj customers are a part of vboxusers group:

vboxusers:x:976:vivek,raj

Lastly, you should utilize the id command to show actual and efficient consumer and group IDs:
id
id vivek
id -nG raj # present all group IDs for raj consumer
id -ng raj # present solely efficient group ID for raj consumer

Conclusion

Now you understand how to make use of varied Linux instructions to indicate all members of a bunch. I recommend you learn the person pages for more information by typing the next man command:
$ man libuser-lid
$ man members
