The scenario: You have one folder, you make a copy of it, then you go about making some changes to the various files in each of the two separate copies.
The problem: You then need to find out what you have changed where. In other words, you need a detailed list of the differences between the two folders…
The solution: Under Linux or Mac OS X you can you the
diff command with the
-r switch, like so
diff -r /my/first/folder /my/copy/of/folder
…and the list of all changes (including files missing or added) will be displayed to your console…
