NAME
ui - show information about local users
SYNOPSIS
ui [-hvVL] [-F separator] [-m separator] [-t format] [-d]
[[-xXO] module1.so [options] [-- [-xXO] module2.so [options] [...]]]
[-c filename] [user] | [-f filename] [...]
DESCRIPTION
ui uses loadable modules to display various information about a local
user. Multiple usernames or filenames (see -f) may be specified. If no
arguments are given or a username or filename is ‘-’, then arguments are
read via standard input.
-d Load the default modules (passwd.so, mail.so and login.so). This can
be used anywhere in the module list.
-t format
Specify an alternate time format for modules which have time values.
See the strftime(3) manual page for format syntax.
-c filename
Load a configuration file. May be used more than once. See below for
details.
-O filename
Load a module. The remaining switches are to be options for this
module. End options for this module by specifying --. This option
may by used more than once. Due to the way module chaining is
implemented, the same module may be loaded more than once.
-x filename
Like -O but chain module1.so output to module2.so input. This will
only work if the module is chainable. You can specify this option
more than once for unlimited chaining.
-X filename
The same as -x but don’t output module1.so info, only pass the
strings to module2.so for processing.
-F separator
Alternate character used to separate fields. Standard escape
sequences are supported.
-m separator
Alternate character used to separate multi string values. Standard
escape sequences are supported.
-f Get information for the owners of the specified files.
-L If the -f option is specified and the file is a symbolic link, get
owner information for the file the link points to and not the link
itself.
-v Be verbose when possible. Some modules may limit their display. This
should show everything available. This is reset for each loaded
module unless specified twice.
-h Display help text. A module must be specified either with the -O
command line option or loaded via configuration file -c for a modules
help text to be displayed.
-V Version information.
RETURN VALUES
Returns 1 on failure and 0 on success. Note that a modules return value
affects this exit status.
FILES
PREFIX/lib/userinfo Default location of loadable modules.
EXAMPLES
The following will load two modules, specify module options and load a
configuration file. Module options end when -- is reached.
ui -O module.so -switches -- -O another.so -- -c filename ‘users‘

CONFIGURATION FILE SYNTAX
There is no default configuration file that will be loaded so you’ll have
to create one and load it with the -c command-line option. Empty lines
and everything to the right of a ’#’ are ignored. If you need a ’#’ in
your options, escape it with a ’\’. This file should contain any modules
you want loaded and their options separated by one or more whitespace
characters on one line per module.
Each module should have a .so filename extension. If a module filename
begins with a ~, it will be expanded to your home directory. Some module
options may require quoting. Single and double quotes are supported and
may also be escaped with a backslash character. Multiple configuration
files may be specified and may also be used with the -O command-line
option. The order of module loading and output is dependent on the order
of the module stack and any module options.
If you want module chaining, put a ’>’ or ’-’ at the beginning of the
module name before any ’~’. This is the same as specifying -x or -X on
the command line, respectively. The following module, which may also be
chained, will be chained to this module.
