Using sed to simply edit items in place usually works like this:
sed -i 's,OLDSTRING,NEWSTRING,g;s,OLDSTRING2,NEWSTRIN2G,g' FILENAME
The semicolon separates search/replace strings and the g makes it replace
all occurrences.
If the text to be replaced has comas (,) you can use / as a delimiter such
as |,#,etc.
