I need to perform a search and replace of text on Solaris 8 with the following conditions:
1. Performed on TEXT files (NOT based on the file extension).
2. The text files must be automatically identified.
3. To be recursively performed on all files within a directory.
4. Output a report on exactly were the text was replaced.
5. Interactive S&R would be a bonus, but not mandatory.
Please direct me to a freeware application (preferably GUI app), or send me a script to do this.
