I often use the find command to search through source code, delete files, whatever. Annoyingly, because Subversion stores duplicates of each file in its .
find
.
I use grep for this purpose. Put this in your ~/.bashrc
export GREP_OPTIONS="--binary-files=without-match --color=auto --devices=skip --exclude-dir=CVS --exclude-dir=.libs --exclude-dir=.deps --exclude-dir=.svn"
grep automatically uses these options on invocation
