conditional replacment with regexps?
 
Hi,

Suppose I have some text with a whole load of a's and b's, how can I create a regexp to replace the a's with b's and the b's with a's?

sed 's/a/-=-TMP-=-/g; s/b/a/g; s/-=-TMP-=-/b/g'

But I guess tr 'ab' 'ba' should work.

Yves.

Suppose I was using emacs though?
