The one place I always get in trouble when it comes to scripting is with quoting. No matter how many times I run into it, read up on it, etc. I can't seem to retain it for some reason. (Probably exacerbated by the fact that I only write scripts once in a while.)

I want to modify a string that contains a ' by using sed. If I were to do it inside of vi, :1,$ s/'/ /g would work fine.

But if I try to do it in a script, normally one would use single quotes around it, which gives sed '/'/ /g/ filename > new.filename . This doesn't work for obvious reasons. But what is the correct way to do this?

I've tried escaping the single quote with a \, I've tried enclosing the lot with double quotes or back quotes instead, but nothing is working. (You can tell I'm flailing without a proper idea -- that's what I mean, I can't seem to retain this quoting stuff.)

Any insights would be *most* gratefully received!
