The "m" means "match". "m" only means treat the string as multiple lines if it's on the end, i.e. /.../m. The leading "m" here is basically useless, but some people like it for clarity. > Then we are grouping with a parenthesis and the "^=" is saying matching > anything up to the "=" The [^=] says "match a characters that is not =". It must be taken as a unit, not just as "^=". > The "+" is a quantifier saying that must match 1 or more times... Correct. > Then the the rest is saying match anything after the "=" The rest says "match =, then match anything". > I guess my question is am I right? Approximately. :) > And I still am not sure where it is saying to assign the first match to > variable $1 and then the rest to variable $2 The parentheses "capture" what they match and stored them in numbered variables. For example: "bar" =~ /(.)(.)/ matches, and stores "b" in $1, and "a" in $2. So does that clear it up any? As mud? As glass? Something in between?
