Hello

I am Morteza Ghorbani

While Working with id utility, I found strange behavior.

Suppose that my username is ‘user1’ , so if I remove user1 from a particular group (e.g. netdev)  by the following instruction :

gpasswd –delete user1 netdev  

then if I enter the ‘id’ command, I will be noted that nothing has been changed and still see the group which I removed the use1 from.

On the other hand, if I enter the command ‘ id user1 ‘, by this way I can see the changes !

In a nutshell,  ‘id’ à does not show the changes while ‘id user1’ shows the changes and its behavior is correct.
