I want to find say : width="100" and remove it from each file in the directory where it is found.

If anybody can tell me this I will be mucho grateful!

thanks for that, works a treat!

I'm a PHP programmer and want to get to grips with shell scripting...where would be a good place to start?

Thanks

I learned most from a linux book with a small chapter about shell scripting plus the bash manual for advanced features. After this, I got some years of experience now. Everyday there is a new feature to find that you didnŽt know yet about...

The bash manual is somewhere in /usr/doc or /usr/share/doc or /usr/local/share/doc or ... youŽll find it

YouŽll need to learn about the many tools that come with the average unix installation. Their interaction makes the real power of scripting.
