Recipe 8.3. Finding a User's UID and GID
8.3.1 Problem
You want to know a quick
way to check the UIDs of users and see what groups they belong to.
8.3.2 Solution
Use the id command:
$ id carla
uid=1000(carla) gid=1000(carla) groups=1000(carla),20(dialout),24(cdrom),25(floppy),
29(audio),30(dip),44(video), 105(windows),432(usb),1001(cdrecording)
8.3.3 Discussion
id has a few options:
- -u
-
Show the UID only.
- -g
-
Show the GID only.
- -gn
-
Show the user's primary group name, instead of the
GID.
