Remove A User From the specific Group In Linux

[Gabriel Turqos]

How can I remove a specific user from the group?

 

[Neemobeer]

usermod -G group1,group2,group3 user this without the -a will drop any groups you don't specify, or you can just go edit the /etc/group file and reboot or you can use gpasswd -d user group

It is easier than you think. Use the usermod command with root privileges. Following example will remove the user george from the root group.

$ sudo usermod -G root george
