commonfile shell script
I am having trouble trying to figure out how to start this shell
script. Here are the instructions: Write a program that will receive two command line parameters which are paths to directories. Your program will do the following: a) Verify that two parameters were passed in and that both of them are paths to directories. b) Determine if there are any common files (files with same name) in the two directories and if so, print out the names of all common files. Any help would be appreciated.
