To quickly find any text string within any text file, try this from a terminal window: grep -l [text to find] [files to look in] For example, grep -l 123abc *.html will list the name of any file in the current directory that ends in .html and contains the string 123abc. (That's a lower-case-L following the GREP) Quite powerful, and fairly fast. Now, if you have some spare time, and want to see what it can really do, try this: su root cd / grep -lr "text to find" * This will tell the OS to find the "text to find" in every file in every directory, all the way down through the tree. The -r flag tells grep to recursively search directories. Of course, OS X has something like 26,000 files, so this can take a very long time!
