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.
