I'm trying to find a tool out there which would hopefully save me hours of work. I have about 15 modules of perl code and 3 huge modules of SQL code (total of about 600 pages of sql). I need to find for each perl module which procedures/functions it uses. Is there any utility out there which will do a comparison of one file to multiple files and find all the similar words? So far I've found some tools which show me the difs.. /edit I found one tool HexEdit which may be what I need but its for mac???
