If i were you i'd do it in perl. Much easier for us mere mortals.
Something like
#!/usr/bin/perl -w
use strict;
my $i;
my @list;
open IN, "< /etc/group" or die "Can't open /etc/group\n";
while (<IN>) {
chomp;
@list = split /[:,]/;
$i = 3;
if ( defined $list[$i] ) {
open OUT, "> $list[0]" or die "Can't open $list[0]\n";
while ( defined $list[$i] ) {
print OUT $list[$i] . "\n";
$i++;
}
close OUT;
}
}
close IN;
good luck! :)
