View Answer

Answer: groupadd,

/usr/sbin/groupadd

Explanation:

The groupadd command creates a new group using the options specified on the command line and the default values from the /etc/login.defs file. It adds an entry for the new group to the /etc/group and /etc/gshadow files. Only the root user or a user with sudo privileges can create new groups using this command. The general syntax for the groupadd command is as follows: groupadd [OPTIONS] GROUPNAME

Some of the common options for the groupadd command are:

-g, –gid GID: Specify the numeric group ID for the new group. If not given, the system will assign the next available GID from the range of group IDs specified in the login.defs file.

-r, –system: Create a system group with a GID chosen from the range of system group IDs specified in the login.defs file. System groups are usually used for some special system operation purposes, like creating backups or doing system maintenance.

-f, –force: Suppress the error message if the group already exists and exit successfully. This option is useful for scripts that need to ensure the existence of a group.

-K, –key KEY=VALUE: Override the default values from the /etc/login.defs file. The valid keys are GROUP_MIN_ID, GROUP_MAX_ID, SYS_GROUP_MIN_ID, SYS_GROUP_MAX_ID, and GID_INCREMENT.
