ZipGrep is a utility that can list and search zip (.war, .ear, .jar, etc) archives for text patterns, without the need to extract the archive's contents.
One of a set of tools we're offering as a way to say thank you for being a part of the community.
With this program you can search for words inside a file. If it find a word it will display it and put the line number in front of it.
I use the command line version where the command is as follows:
grep -in "<Search Item>" *.[extension]
Replace the <Search Item> for the word that you looking for and the [extension] for the proper extension like .html
