Is there any program that will scan two code files, compare, and show you what is different between them. I need such a system as I am building a website using plugins that are regularly updated, however I need to edit the plugins to provide some of the functionality my client wishes to have. I want this to just reduce the amount of time it takes to make the changes to the files in the plugin before it is uploaded to the server and updated.

  • you mean something like diff command on unix, or [beyond compare](http://www.scootersoftware.com/) or [winmerge](http://winmerge.org/)? – aishwarya Dec 04 '11 at 04:33
  • compare between version numbers, that will save up so much trouble, but has great responsibility on developers on updating the numbers. – mauris Dec 04 '11 at 07:10

Any diff tool can do this - the unix "diff" is a command-line example, a GUI option for windows is Sourcegear's DiffMerge. Many text editors also have a diff option built in. Just google for "diff tool" and you'll have many to choose from.
