I have an application that formerly was written in bash but latter got many scripts being written both in bash and perl. Now I want to use a function that is contained in a perl-script - that is used by other perl scripts using 'require' - from a bash script. I need to call it passing a string to it and get the result from it (a string also). I've looked through several bash guides but did not find a solution. So, my question is, How to do that?
