I work on a mac OSX 10 +.
I an looking for some software that can enable me to change a word of text in a file ( php file or otherwise ) without having to open each file individually.
Let me explain - I have a folder named 'code folder' and it contains 72 php files, I want to remove specific word from all the 72 php files without having to open every file and scan through them individually and find and replace the word I am looking for.
Does anyone know of any software for the Mac that will enable me to do this, or if not how it could be do otherwise.
Many thanks in advance for any help you may be able to me.
