+ Moved all internal definitions from usermgmt.h to user.c + Added prototypes to usermgmt.h + Allow defaults to be set at build time + Check the effective uid is 0 if any data is to be modified + Check all numeric uids and gids really are numeric + Fix a bug (reported by lenb at sasquatch.com) where new ranges were appended to old ranges, rather than replacing them + Add userinfo(8) and groupinfo(8) utilities (if EXTENSIONS is defined), whereby user and group information can be displayed. Add manual pages for new utilities. Add front-end calling from user(8) and group(8) accordingly. + Make all functions visible outside the user.c file again. User and group manipulation may be split out into a separate shared lib in the future + Split off main function into a separate main.c + Changed default group to be "users" + Changed despatch table for commands to work in a more sane manner + Added "default-group" target to Makefile, so that the default group can be made easily.

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility removes a user from the system, optionally
|
|
removing that user's home diretory and any subdirectories.
|
|
.Pp
|
|
The first format of the command shown above (utilising the -D option)
|
|
sets and displays the defaults for the
|
|
.Nm
|
|
utility.
|
|
.Bl -tag -width Ds
|
|
.It Fl D
|
|
without any further options, -D will show the current defaults which
|
|
will be used by the
|
|
.Nm
|
|
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.
|
|
.It Fl p Ar preserve-value
|
|
sets the preservation value. If this value is one of "true", "false",
|
|
or a non-zero number, then the user login information will be preserved.
|
|
.El
|
|
.Pp
|
|
The following command line options are recognised:
|
|
.Bl -tag -width Ds
|
|
.It Fl p
|
|
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 the the false(1) 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.
|
|
.It Fl r
|
|
remove the user's home directory, any subdirectories,
|
|
and any files and other entries in them.
|
|
.It Fl v
|
|
perform any actions in a verbose manner.
|
|
.El
