That is the wrong syntax. You have quoted the 'n'. That is why you see the 'n' show up in the display. Try this: printf "<pre>\nSome text\n</pre>\n" | sed '/<pre>/a\ ' And by that I mean literally 'a' followed by a single backslash followed by a single newline. Just like in the example. :-) > P.S. Hmm, while testing before sending this I discovered that > sed '/<pre>/a\\' works. Not what I would have expected. That is an interesting quirk of GNU sed. But note that other sed implementations handle that differently. It isn't portable. For example: sed: Function /<pre>/a\\ cannot be parsed. Bob
