Linux/UNIX: Find Which Groups Do I Belong To

To find out which groups you belong to in Linux or other Unix-like operating systems, you can use the groups command. This command will display a list of all the groups that you are a member of.

For example, to view the groups that you belong to, you can use the following command:

groups

This will output a list of groups, separated by spaces, similar to the following:

users wheel

The groups that you belong to are determined by your user account and are specified in the /etc/passwd file. Each user account is associated with a primary group, which is specified in the passwd file, as well as any number of additional groups.

You can use the id command to view more detailed information about your user account and the groups that you belong to. For example, to view your user ID (UID) and group ID (GID), you can use the following command:

id

This will output a line similar to the following:

uid=1000(user) gid=1000(user) groups=1000(user),10(wheel)

The uid and gid values indicate your user ID and group ID, respectively. The groups value lists all the groups that you belong to, including your primary group.
