I use rcs for revision control in my scripts. One such script gets replicated to several client directories on a recurring basis to ensure that they are running the latest code. As a result, I assign a varible as the revision number within rcs:

my $rcs = '$Id:$';

this ends up expanding to a value such as:

$Id: dnsmod,v 1.17 2001/07/20 20:10:14 root Exp root $

I am really only interested in grabbing the 1.17 portion of the string. For now, I am using some dirty code that I really am unsatisfied with:

my $rcs = '$Id: dnsmod,v 1.17 2001/07/20 20:10:14 root Exp root $'; my ($garbarge, $garbage, $version) = split(/ /, $rcs);

This way, I grab $version and stick it within my code in an appropriate place for it to show up and let users match that they are using the newest rev.
I read over the split tutorial and it shows options for assigning multiple values based on the split. I am just hoping that my $garbage variables can be taken out of the mix.
I know that I can use an @array and pull the value with something like:

@array = = split(/ /, $rcs); $version = $array[3];

But are these really my only options?
