you can use the standard find/replace in any GUI or text editor. I personally prefer vi (or vim in some cases) its a rather simple syntax:

Quote:
Give a skeptic and inch... and he'll take a mile.

and typed


:s/take a mile/measure it/

I would be left with

Give a skeptic and inch... and he'll measure it.
that is what you would do on the line you want to edit, now if you want to make this a global add a g at the end of the command:

Code:
:s/take a mile/measure it/g

This sounds a lot like a homework question, and per the LQ rules we won't give you specific answers. But we can help guide you to a solution.

So to start with, what have you attempted so far, and where exactly are you having trouble?

^This, and please define "half of a line". In your example, "this" is not half of the line.
