Well, OK, taking on the challenge, how about:

#!/usr/bin/perl
sub u { local($name)=getpwuid($_[0]); $name && "($name)";}
sub g { local($name)=getgrgid($_[0]); $name && "($name)";}
sub bynum { $a - $b; }
print "uid=$<",&u($<);
print " gid=", $(+0,&g($();
print " euid=$>",&u($>) if $> != $<;
print " egid=", $)+0,&g($)) if $) != $(;
@groups=split(' ',$(); shift(@groups);
print " groups=", join(',',sort bynum grep(($_ .= &g($_)) || 1, @groups))
	unless $#groups < $[;
print "\n";

Something like that, Larry?

print pack('C25',grep($_ = 32 + y/ / /, split(/\n/, <<END)));
