gpasswd question

[jmkmx]

Hello Forum,

Is there a way to remove multiple users from a group with gpasswd or any other tool?
I know you can add multiple users by entering the following:

sudo gpasswd -M userA,userB,userC mygroup

But can I don't know if you can do the opposite.

Any suggestions would be highly appreciate it!!!

Open a terminal and type

man gpasswd

That will tell you what you can do with gpasswd.

If the man pages aren't good for you, do an online search for sites which might be a little more informative and easy to follow, one such site at the link below.

You misunderstand the way the '-M' option works. It doesn't add members to the group, it sets the group to have these (and only these) members. If mygroup has the users UserB,UserC,UserD, and UserE then the result of 'gpasswd -M UserA,UserB,UserC' is that UserA is added to the group and UserD and UserE are removed from it.

Another way to remove multiple users from a group is looping over a list of users you want removed and run the command to remove each user like so:

for user in username anotheruser onemore ; do gpasswd -d $user mygroup; done

This may seem old school, but I'd use sudoedit on the 3 relevant files in /etc/. What each field means is well documented in the manpage for each. The file formats are pretty simple.
