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.
