Yes, I have tested it here (but only after you asked). I only have one user so it's not a very thorough test case.

Do you get an error, or doesn't it do what you expect?

Where do you want the real name to be displayed?

Code:
#!/bin/bash
users | tr '. ' '
' | sort -u | while read user
do
  sed -n "s/:[^:]*:[^:]*$//;s/^$user:[^:]*:[^:]*:[^:]*://p" /etc/passwd
  ps -U "$user"
done

The sed script is the moral equivalent of grep "^$user:" /etc/passwd | cut -d: -f5 which is arguably more readable. Maybe you want to use that instead, actually.

Gedcom::Individual(3pm) 				User Contributed Perl Documentation				   Gedcom::Individual(3pm)

NAME
Gedcom::Individual - a module to manipulate Gedcom individuals Version 1.16 - 24th April 2009 SYNOPSIS
use Gedcom::Individual; my $name = $i->name; my @rel = $i->father; my @rel = $i->mother; my @rel = $i->parents; my @rel = $i->husband; my @rel = $i->wife; my @rel = $i->spouse; my @rel = $i->siblings; my @rel = $i->brothers; my @rel = $i->sisters; my @rel = $i->children; my @rel = $i->sons; my @rel = $i->daughters; my @rel = $i->descendents; my @rel = $i->ancestors; my $ok = $i->delete; my @fam = $i->famc; my @fam = $i->fams; DESCRIPTION
A selection of subroutines to handle individuals in a gedcom file. Derived from Gedcom::Record. HASH MEMBERS
None. METHODS
name my $name = $i->name; Return the name of the individual, with spaces normalised. cased_name my $cased_name = $i->cased_name; Return the name of the individual, with spaces normalised, and surname in upper case. surname my $surname = $i->surname; Return the surname of the individual. given_names my $given_names = $i->given_names; Return the given names of the individual, with spaces normalised. soundex my $soundex = $i->soundex; Return the soundex code of the individual. This function is only available if Text::Soundex.pm is available. sex my $sex = $i->sex; Return the sex of the individual, "M", "F" or "U". Individual functions my @rel = $i->father; my @rel = $i->mother; my @rel = $i->parents; my @rel = $i->husband; my @rel = $i->wife; my @rel = $i->spouse; my @rel = $i->siblings; my @rel = $i->older_siblings; my @rel = $i->younger_siblings; my @rel = $i->brothers; my @rel = $i->sisters; my @rel = $i->children; my @rel = $i->sons; my @rel = $i->daughters; my @rel = $i->descendents; my @rel = $i->ancestors; Return a list of individuals related to $i. Each function, even those with a singular name such as father(), returns a list of individuals holding that relation to $i. More complex relationships can easily be found using the map function. eg: my @grandparents = map { $_->parents } $i->parents; delete my $ok = $i->delete; Delete $i from the data structure. This function will also set $i to undef. This is to remind you that the individual cannot be used again. Returns true iff $i was successfully deleted. Family functions my @fam = $i->famc; my @fam = $i->fams; Return a list of families to which $i belongs. famc() returns those families in which $i is a child. fams() returns those families in which $i is a spouse. perl v5.14.2 2012-04-12 Gedcom::Individual(3pm)
