The string may appear more than once in a file. Try the following (make sure you have a backup first ;)) perl -pi -e 's/STRING_TO_FIND/STRING_TO_REPLACE_WITH/g' filename e.g. to replace all instances of foo with bar in a file called test you'd do: perl -pi -e 's/foo/bar/g' test You'd need to write a shell script to recursively run this on in each subdirectory.
