Is there an option to make sed fail if pattern not found?

Question

I need to find and replace some patterns in some files, but I need it to return 1 or something if a pattern is not found.

Can I do this with sed alone or do I need to check whether the pattern exists with another command?

Any suggestions?

Check out this answer: How to check if sed has changed a file.

Its pretty much the same as you are asking, its suggesting you use awk or output to a different file and diff the two files.
