Is it possible to compare two directories with Diff?
However, the output is cluttered with a lot of files that only exist in one directory, but not the other. Can I force diff (or use another tool) to only show files that differ AND exist in both directories?
Is there a way to change the files in diff?
The diff software does not actually change the files it compares. However, it can optionally generate a script (if the -e option is specified) for the program ed or ex which can be used to apply the changes.

How to check if DIR1 is in same folder as Dir2?

Which is the best tool to compare directories?
Meld ( http://meldmerge.org/) does a great job at comparing directories and the files within. vim’s DirDiff plugin is another very useful tool for comparing directories. It not only lists which files are different between the directories, but also allows you to inspect/modify with vimdiff the files that are different.
