// search for foo in all .php files in the dir tree, but skip .svn directories

find . -path .svn -prune -o -name *.php | xargs grep foo

find . -name          *.php -exec sed -i 's/oldtext/newtext/g' {} \;
find . -name .svn -prune -o -exec sed -i 's/oldtext/newtext/g' {} \;

My understanding:

find files starting with . (local directory)

-name .svn -prune means if you find .svn for a filename (directory name), skip it.

-o OR

-exec execute

sed -i sed is the stream editor. -i means change the files in place.

's/new/old/g' Substitute old text for new text Globally.

{} sends the filenames that find found to sed

\; terminates the -exec from find, and \ escapes it so the shell won't think it means to end its command.
