rmuser Command

Purpose

Removes a user account.

Syntax

rmuser [ -p ] Name

Description

The rmuser command removes the user account identified by the Name parameter. This command removes a user's attributes without removing the user's home directory and files. The user name must already exist as a string of 8 bytes or less. If the -p flag is specified, the rmuser command also removes passwords and other user authentication information from the /etc/security/passwd file.

Only the root user or users with UserAdmin authorization can remove administrative users. Administrative users are those users with admin=true set in the /etc/security/user file.

You can use the Web-based System Manager Users application (wsm users fast path) to run this command. You could also use the System Management Interface Tool (SMIT) smit rmuser fast path to run this command.

Flags

-p	Removes user password information from the /etc/security/passwd file.

Access Control: This command should grant execute (x) access only to the root user and members of the security group. This command should be installed as a program in the trusted computing base (TCB). The command should be owned by the root user with the setuid (SUID) bit set.
