73 Removes the username from all groups to which it belongs in
75 (If a group becomes empty and the group name is the same as the username,
76 the group is removed; this complements
78 per-user unique groups).
82 politely refuses to remove users whose uid is 0 (typically root), since
83 certain actions (namely, killing all the user's processes, and perhaps
84 removing the user's home directory) would cause damage to a running system.
85 If it is necessary to remove a user whose uid is 0, see
87 for information on directly editing the password file, by which the desired
90 entry may be removed manually.
92 If not running "affirmatively" (i.e., option

97 that you wish to remove the user. If the user's home directory is owned
100 asks whether you wish to remove the user's home directory and everything
105 operates, it informs the user regarding the current activity. If any
106 errors occur, they are posted to standard error and, if it is possible for
108 to continue, it will.

115 the affirmative (i.e., yes). A username must also be specified on the

150 utility does not comprehensively search the file system for all files
151 owned by the removed user and remove them; to do so on a system
152 of any size is prohibitively slow and I/O intensive.
153 It is also unable to remove symbolic links that were created by the
160 file systems do not contain information
161 as to who created them.
162 Also, there may be other files created in
165 .Pa /var/mail/ Ns Ar username
167 .Pa /var/mail/.pop. Ns Ar username
168 that are not owned by the removed user but should be removed.
