USERDEL(8)						    BSD System Manager's Manual 						USERDEL(8)

NAME

     userdel -- remove a user from the system

SYNOPSIS

     userdel -D [-p preserve-value]
     userdel [-rSv] [-p preserve-value] user

DESCRIPTION

     The userdel utility removes a user from the system, optionally removing that user's home directory and any subdirectories.

     Default values are taken from the information provided in the /etc/usermgmt.conf file, which, if running as root, is created using the built-
     in defaults if it does not exist.

     The first form of the command shown above (using the -D option) sets and displays the defaults for the userdel utility.

     See user(8) for more information about EXTENSIONS.

     -D      Without any further options, -D will show the current defaults which will be used by the userdel utility.	Together with one of the
	     options shown for the first version of the command, -D will set the default to be the new value.  This option is included if built
	     with EXTENSIONS.

     -p preserve-value
	     Set the preservation value.  If this value is one of 'true', 'yes', or a non-zero number, then the user login information will be
	     preserved.  This option is included if built with EXTENSIONS.

     In the second form of the command, after setting any defaults, and then reading values from /etc/usermgmt.conf, the following command line
     options are processed:

     -p preserve-value
	     Preserve the user information in the password file, but do not allow the user to login, by switching the password to an
	     ``impossible'' one, and by setting the user's shell to the nologin(8) program.  This option can be helpful in preserving a user's
	     files for later use by members of that person's group after the user has moved on.  This value can also be set in the
	     /etc/usermgmt.conf file, using the 'preserve' field.  If the field has any of the values 'true', 'yes', or a non-zero number, then
	     user information preservation will take place.  This option is included if built with EXTENSIONS.

     -r      Remove the user's home directory, any subdirectories, and any files and other entries in them.

     -S      Allow a samba user name (with a trailing dollar sign) to be deleted.  This option is included if built with EXTENSIONS.

     -v      Perform any actions in a verbose manner.  This option is included if built with EXTENSIONS.

     Once the information has been verified, userdel uses pwd_mkdb(8) to update the user database.  This is run in the background, and, at very
     large sites could take several minutes.  Until this update is completed, the password file is unavailable for other updates and the new
     information is not available to programs.

EXIT STATUS

     The userdel utility exits 0 on success, and >0 if an error occurs.

NAME

     usermgmt.conf -- user management tools configuration file

SYNOPSIS

     usermgmt.conf

DESCRIPTION

     The usermgmt.conf file defines the default values used by the user management tools, useradd(8) and friends.

     Options in this file can be set by manually editing /etc/usermgmt.conf or using the -D option to useradd(8).

     base_dir	sets the base directory name, in which new users' home directories are created when using the -m option to useradd(8).

     class	sets the default login class for new users.  See login.conf(5) for more information on user login classes.

     expire	sets the default time at which the current password expires.  This can be used to implement password aging.  Both the expire and
		inactive fields should be entered in the form ``month day year'', where month is the month name (the first three characters are
		sufficient), day is the day of the month, and year is the year.  Time in seconds since the epoch (UTC) is also valid.  A value of
		0 can be used to disable this feature.

     group	sets the default primary group for new users.  If this is '=uid', then a uid and gid will be picked which are both unique and the
		same, and a line will be added to /etc/group to describe the new group.  It has the format:
		      group gid | name | =uid

     homeperm	sets the default permissions of the newly created home directory if -m is given to useradd(8).	The permission is specified as an
		octal number, with or without a leading zero.

     inactive	sets the default time at which new accounts expire.  A value of 0 can be used to disable this feature.	Also see the expire field.

     password	specifies an already-encrypted default password.

     preserve	If this value is one of 'true', 'yes', or a non-zero number, then the user login information will be preserved when removing a
		user with userdel(8).

     range	specifies the uid boundaries for new users.  If unspecified, the default is ``1000..60000''.  It has the format:
		      range starting-uid..ending-uid

     gid_range	specifies the gid boundaries for new groups.  If unspecified, the default is ``1000..60000''.  It has the format:
		      gid_range starting-gid..ending-gid

     shell	sets the default login shell for new users.

     skel_dir	sets the default skeleton directory in which to find files with which to populate the new user's home directory.
