However, what if I wanted to exclude one or more characters in this class from the replacement? I tried using sed -e 's/[<list of characters>]/<replacement character>/g' but that doesn't seem to work...
Ignoring the g at the end of the command, the command will substitute the first instance from the list of characters encountered in the text with the replacement character. The g means it will happen for every instance. Cheers MichaelW
