Re^5: regex trouble

You probably want to do something like

my $var = `command`;

Notice that the single quotes were replaces by backticks. There are certain problems with using backticks, but it's usually OK to use them to run a simple and safe command.

Also, your current code will only capture v09.11. If you want to capture v09.11-e020, use this:

my ($exp) = $var =~ m/(v\d{2}\.\d{2}-[a-z]\d{3})/;

You probably only need one opening bracket in the beginning and one closing in the end: `m/(v\d{2}\.\d{2}-[a-z]\d{3})/` Brackets should usually match - for every opening bracket there must be one closing bracket.	[reply] [d/l]
