I realize that this is not really a FreeBSD question, but I like this
mailing list and the answers that are sent to it :).
My question is:
How do I have perl return me the first and only the first match to a
regular expression? I know that I can return /all/ matches to an
array, and get the first one, but I only want to have it evaluate as
far as the first match and then stop.
For example, given the string xayxbyxcy and the regular expression
x.y, I want it to return to me only xay and not evaluate any further.
From Learning Perl:
"We can force any multiplier to be non-greedy (or lazy) by
following it with a question mark:
$_ = "a xxx c xxxxxxxxx c xxx d";
Here, the a.*?c now matches the fewest characters between the a and
he c, not the most characters. This means that the leftmost c
ismatched, not the rightmost....."
Thanks in advance.
