File differences

diff -BNarq

The best use for file differences,
-b --ignore-space-change Ignore changes in the amount of white space.
-w --ignore-all-space Ignore all white space.
-B --ignore-blank-lines Ignore changes whose lines are all blank.
-a --text Treat all files as text.
-r --recursive Recursively compare any subdirectories found.
-N --new-file Treat absent files as empty.
-q --brief Output only whether files differ.


If the sources are checked out from svn,
I would remove all the .svn directories and do the diff, issuing
find . -iname ".svn" -exec rm -frv '{}' \;
