An alternative but less general question would be: How to use groupmod based on a group id?

man groupmod indicates a group can only be looked up by group name. This is seemingly a problem for groups that only have an id and not a name, see group with id == 999 below:

~$ id
uid=1000(brandon) gid=1000(brandon) groups=1000(brandon),999

Create a new group with specific gid. You can do this with groupadd:

groupadd -G 999 mygroup
