I'm not sur it's the most efficient solution, but you could use
urlview . This utility browses a text file and looks for URLs,
and returns them. This has the disadvantage of adding another
dependency and maybe it's not worth it.
You will note that the urlview man page contains the regular
expression for a URL. Here it is:
(((http|https|ftp|gopher)|mailto):(//)?[^ <>"\t]*|(www|ftp)[0-9]?\.[-a-z0
-9.]+)[^ .,;\t\n\r<">\):]?[^, <>"\t]*[^ .,;\t\n\r<">\):]
It's rather ugly.
