Re: changing only the first two matches of a regex

I would do something like:

s/(\d+_)(.*)?(\d+_)(.*)/$1$2/;

With what you have above, the replace should be $2$4, since you have 4 grouping operators there. Or you could just have "\d+_", or use "(?:\d+_)" as to use $1$2 as others have done later in this thread. Dr. Michael K.
