  userdel - Deletes a user login account from the system.



  /usr/sbin/userdel [-r] login


  /usr/sbin/userdel [-D] [-r] [-R] [-ttype] [-P] [-x extended_option] login


  -D	  When enhanced	security mode is enabled this option deletes the user
	  account from /etc/passwd file	and the	enhanced security protected
	  password database.

  -r	  Removes a user's home	directory from the system. This	directory
	  must exist and must be owned by the user whose login account is
	  being	deleted.

  -R	  When enhanced	security is enabled, retires the account without
	  deleting entries from	the databases or removing home directories.

  -t type Removes a local plus (+) or local minus (-) NIS user from the	user
	  database. The	value of the type parameter can	be + or	-.

  -P	  Removes PC accounts only, without deleting the user's	existing UNIX

  -x extended_option [extended_option]...
	  Extended_options are of the form attribute=value. You	may enter any
	  number of extended options (within the character limit of the	com-
	  mand line) by	separating each	option with a space. Alternatively,
	  they may be entered separately following the -x switch. Note that
	  some extended	options	are only available under specific system

	  The following	sets ofextended_option attributes are available:

		  The value 1 indicates	that the account to be deleted is
		  local. The value 0 indicates that the	account	is to be
		  deleted from the NIS database.

		  The value 1 indicates	that the account to be deleted is a
		  NIS user account. You	must be	on the NIS master to delete a
		  NIS user.

	  The following	extended_option	attribute is available for PC group
	  administration if the	Advanced Server	for UNIX (ASU) is configured
	  and running:

		  The value of the pc_synchronize=n attribute can be 0 or 1.
		  If set to 1, both PC and UNIX	accounts will be affected by
		  delete operations. If	set to 0, only UNIX accounts will be
		  affected by delete operations	and the	PC account will	be

  login	  Specifies an existing	login account on the system.


  The userdel command is part of a set of command line interfaces (CLI)	that
  are used to create and administer user accounts on the system. When The
  Advanced Server for UNIX (ASU) is installed and running, the userdel com-
  mand can also	be used	to administer PC accounts. Accounts can	also be
  administered with the	/usr/bin/X11/dxaccounts	graphical user interface
  (GUI)	or the sysman(8) Accounts menu.

  Different options are	available depending on how the local system is con-

    +  In the default UNIX environment,	user account management	is compliant
       with the	IEEE POSIX Standard P1387.3.

    +  If enhanced (C2)	security is configured,	additional options and
       extended	options	can be used.

    +  The CLI is backwards-compatible,	so all existing	local scripts will
       function. However, you should consider testing your account management
       scripts before using them.

  The userdel command deletes a	user's login account from the system and
  makes	the login-related changes in the appropriate system files determined
  by the current level of security. Additionally, the files and	directories
  contained under the user's home directory can	be removed from	the system.

  The -x options local and distributed let the system administrator specify
  whether the user to be deleted is local or distributed by NIS. If these
  options are not specified on the command line, the system deletes the	user
  from the appropriate database	as specified by	the system defaults. System
  defaults for users may be set	with the usermod -D option. In the absence of
  any defaults,	userdel	deletes	a local	user. Certain combinations of these
  settings are incompatible and	produce	an error: it is	invalid	to set both
  values to 0 or both of them to 1.


  Note the following restriction that applies to this release:

  You must have	superuser privilege to execute this command.


  The userdel command exits with one of	the following values:

  0	  Success.

  1	  Failure.

  2	  Warning.


   1.  The following example removes the local plus (+)	user, newuser1:
	    % userdel -t + newuser1

   2.  The following example removes the NIS user, newuser4, from the NIS
       master database:
	    % userdel -x distributed=1 newuser4

   3.  The following example deletes the user, xyz, and	removes	the user's
       home directory:
	    % userdel -r xyz

   4.  The following example deletes the UNIX account for studentB, removing
       the home	directory and its corresponding	PC account.
	    % userdel -r -x  pc_synchronize=1 studentB


  The userdel command operates on files	for the	specific level of system
