Free search and replace software to help you efficiently find and replace text in files
Free Text Search and Replace Utilities
This page lists software that will allow you to easily and efficiently search and replace text or blocks of text in a set of files or folders/directories. Most if not all of the programs will allow you to search and replace literal text, while others will also allow you to specify regular expressions to find and replace the text; that is, you can ask the software to replace, say, every instance of "happy" that occurs immediately before "birthday" with "joyous" (or whatever).
Note that this page does not list commercial software like PowerGrep (download free trial here) that provides a large set of facilities (including regular expressions), convenience, speed, safety (you can preview the replacement before it happens to make sure it does what you want, you can automatically create backup files if you wish and you can also undo the replacements if you realise you've made an error), the ability to search Word documents, Excel documents, PDF files, compressed archives (like zip files), text and binary files, etc. It's expensive, but in my opinion, if you work with text extensively as programmers and webmasters tend to do, the productivity gain is enough to make it worth the price.
