sed question, given a set of char's, replace char's not in the set
Hello, and thanks for taking time to read my question.
I would like to use sed, or "tr", to replace any invalid character with a <space>. My set of valid characters are a-z A-Z 0-9 ! " & , ( ) + ' ? = @ / . - If the line contains any characters not in the set listed above, I would like to replace each invalid one with a <space>. My attempt at this is: sed 's/[^a-zA-Z0-9!"&,()+\`?=\@;\/\.-]/ /g' but this will not quite do it. It does not do a one for one replace of bad characters. thank you for any advice

Thanks Perderabo, it is working :)
I'm not sure why it wasn't before, but I copied and pasted your exact text and it does work. This is my first attempt at using SED and I'm finding it a bit tricky to get the syntax down. Thank You for the assistance, much appreciated.
