groupmod:tldr:59b0d

This command is used to modify the ID (GID - Group ID) of an existing group in a Linux system, with the assistance of the "sudo" command that provides superuser privileges.

Here's the breakdown of the command:

• "sudo": It allows the command to be executed with administrative/superuser rights. This is typically needed when modifying system-related configurations.
• "groupmod": This is the command used to modify group properties.
• "--gid ${new_id}": This part specifies the new Group ID you want to assign to the group. "${new_id}" is a placeholder for the actual Group ID you wish to set.
• "${group_name}": This identifies the name of the group you want to modify. "${group_name}" is also a placeholder for the actual group name.

By running this command, you can change the Group ID of an existing group to the desired new ID, therefore altering the group's identity and permissions within the system.
