To modify a user’s login definition, use the usermod command. This command modifies the system files in the home directory and supplementary groups of a user. It also makes changes to the password file comment field, normally done with the chfn(1) utility. Using the usermod command also creates an entry for the user in a new home directory, if the old one does not exist. Finally, the usermod command disables the account if the password expires.
The usermod command is also useful for changing a default user group and a user’s default user name. However, this is only used occasionally, such as when adding users to a sudo group, which replaces user groups. Use the usermod command when necessary to prevent users from accidentally changing the user group. It can be a little confusing, but it’s very useful when you need to modify a user’s default group.
