Hello, I am new to ruby. I have a thrid party application that stores configuration settings in an ASCII/TEXT file. I need to map each function within the application to what lines it modifies in the text file. Every time I save the session, it creates a *.bak_YYMMDDHHmmss of the previous version of the file. I am looking to develop a simple script that I would loop through a directory and then compare the oldest *.bak_YYMMDDHHmmss with the next newest *.bak_YYMMDDHHmmss, until it reached the newest file. The script would append the differences to a text file. A nice to have is a start and stop funcation, where I could have it watch a directory and when ever a new *.bak_YYMMDDHHmmss file appears it will compare the files. I am looking for resoucres on how to program this script. Thanks jlimited -- Posted via http://www.ruby-forum.com/.
