Convert 4 ms dos scipts into perl or bash scripts and add small menu driven functionality

I have four or five msdos scripts I need converted over to eother Perl or Bash. These are very short scripts. Three of the scripts generates another script, the other two scripts look at a file and check for a specific string. After they are converted I would like a menu driven interface created so that it would perform specific tasks. IE...I run script. Menu pops up. Would you like to do a b c d e f g or h. I choose h. It asks for specific info and generates a text file to a destination that I desire with specific content. It should do error checking and test for errors in the input etc. It should be one script with a module and "skeleton stubs" with instructions on how to include additional modules should be included. Code needs to be well documented. These scripts will be run under perl / bash on a windows or unix setup. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
