Hi Scorreg,

In perl we most often we use directl pattern matching. This 'm' is nothin but the match operator, often used in conjunction with the bind operator(~).
'^' just signifies the start of the pattern and '!' is delimiter.

You can write the same as ......

=~ {^(/.*)/bin/xx}

Now the 'm' is absent and '{' and '}' are delimiters!!

Actually the 'm' is necessary unless '/' is used as delimiter. So, m{} but not {}, as {} means something else in Perl (reference to hash literal).
