Before moving on to use SVN, I used to manage my project by simply keeping a /develop/ directory and editing and testing files there, then moving them to the /main/ directory. When I decided to move to SVN, I needed to be sure that the directories were indeed in sync.
So, what is a good way to write a shell script [ bash ] to recursively compare files with the same name in two different directories?
Note: The directory names used above are for sample only. I do not recommend storing your code in the top level :).

Click on directory comparison and move to the next interface. Select the directories you want to compare, note that you can add a third directory by checking the option “3-way Comparison”. Once you selected the directories, click on “Compare”.
Click on the “Select Files or Folders” tab in the far left, to start a new comparison. Each comparison you run opens in a new tab. To start a new comparison, click on the “Select Files or Folders” tab in the far left, change the targets and click “Compare” again.
The diff command has a -r option to recursively compare directories:
diff -r /develop /main
diff -rqu /develop /main
It will only give you a summary of changes that way :)
If you want to see only new/missing files
diff -rqu /develop /main | grep "^Only
If you want to get them bare:
diff -rqu /develop /main | sed -rn "/^Only/s/^Only in (.+?): /\1/p"
