User(3pm) User Contributed Perl Documentation User(3pm)


User - API for locating user information regardless of OS


  use User;
  my $cfg = Config::IniFiles->new
          -file    => sprintf("%s/%s", User->Home, ".ncfg"),
          -default => 'Default'
  print "Your login is ", User->Login, "\n";


This module is allows applications to retrieve per-user characteristics.


Returns a location that can be expected to be a users "Home" directory on either Windows or Unix.

While one way of writing this would be to check for operating system and then check the expected location for an operation system of that type, I chose to do the following:

 sub Home {
  return $ENV{HOME}        if $ENV{HOME};
  return  "";

In other words, if $HOME is defined in the user's environment, then that is used. Otherwise $USERPROFILE is used. Otherwise "" is returned.

A contribution for Macintosh (or any other number of OS/arch combinations) is greatly solicited.

Returns login id of user on either Unix or NT by checking "getlogin", "getpwuid", and various environment variables.


File::HomeDir seems to be a very well-done update of the same concept as this module.

T.M. Brannon,

I am grateful for additions by Rob Napier and Malcom Nooning.


I would like to offer profuse thanks to my fellow perl monk at, the_slycer, who told me where HOME could be found on Windows machines.

I would also like to thank Bob Armstrong for providing me with the text of the copyright notice and for including this in the Debian Linux distribution.
