My quick version. Not tested, as I currently have no access to a machine with Term or ps, so feel free to correct :)
#!perl
use Term::Size;
($width) = Term::Size::chars; ## Remove parens?
%usercolor = ( ## Easy to change and add more!
root => "^[[0;31m",
scalar getpwuid($<) => "^[[0;34m",
DEFAULT => "^[[0;36m",
);
%color = ( ## Also easy to change
tty => "^[[0;33m",
pid => "^[[1;30m",
pcpu => "^[[0;37m",
pmem => "^[[1;37m",
cmd => "^[[1m",
);
for (`ps auxfw`) {
($user,$pid,$pcpu,$pmem,
undef,undef,undef,undef,undef,undef,$cmd) = split(/\s+/, $_);
$usercolor = $usercolor{$user} || $usercolor{'DEFAULT'};
## Symbolic refs would work nice below too
$tty = "$color{'tty'} $tty";
$pid = "$color{'pid'} $tty";
$pcpu = "$color{'pcpu'} $tty";
$pmem = "$color{'pmem'} $tty";
$cmd = "$color{'cmd'} $tty";
$out = "$usercolor $user $tty $pid $pcpu $pmem $cmd";
print substr($out, 0, ($width+(7*6)-3));
}
