So, unless your version of sed is extremely strange, I think you've simplified the problem a little too far, reducing it into something which doesn't actually demonstrate your problem. Could you post the actual expression you're having problems with please?
Corona, sorry I got careless cutting and pasting, the grep command was
Code:
grep "[a-z]" temp2.txt

I just tried it again and the result was correct.

The sed example in the post is an example of an expression that exhibits the problem on my system (apparently not others'). I verified that also.

Here is something that is easier to cut and paste to the command line.
Code:
echo abAB | sed -r "s/[a-z]/x/g"

The result is xxxx on my machine. Not the expected xxAB.

Perhaps I do have a strange version of sed. One thought is whether it could be that the regex library not correct for the sed version. I don't know if that is the case or how to check.

Scrutinizer, Yes it works with classes, but that doesn't solve the problem.
