Search for a string in a selection of files

How to search for a string in a selection of files (-exec grep ...). find . -exec grep "www.athabasca" '{}' \; -print This command will search in the current directory and all sub directories. All files that contain the string will have their path printed to standard output. If you want to just find each file then pass it on for processing use the -q grep option. This finds the first occurrance of the search string. It then signals success to find and find continues searching for more files. find . -exec grep -q "www.athabasca" '{}' \; -print This command is very important for process a series of files that contain a specific string. You can then process each file appropriately. An example is find all html files with the string "www.athabascau.ca". You can then process the files with a sed script to change those occurrances of "www.athabascau.ca" with "intra.athabascau.ca".
