replacing two reciprocal words in huge number of scripts

I have a huge number of scripts in MATLAB. I need to write a new script that will search text of script files and replace "ref" wherever it finds "mov" and also replaces "mov" wherever it finds "ref". I'm confused as apparently I can't simply write a script that replaces "mov" and "ref" and then replaces "ref" with "mov" .

Any input is much appreciated.

Three steps:

1. Replace ref with syzygy
2. Replace mov with ref
3. Replace syzygy with mov

For the script itself, you should be able to use the regexprep() command to do the replacement.

I'd have your script use questdlg() to show you the line of text you're planning on doing the replacement on and ask the user for confirmation. That way you can make sure you don't replace something you don't want, like if you have the word "move" or "reference" in a comment or something like that.

Brilliant. Thanks
