I am new to Unix and have a simple question. I would like to do three sed replacements in a large text file. The command I am using is as follows....
The : need to be the search to identify specific :A, :B, :C in the files from A, B, C and replace with :X, :Y, :Z.
When I run the command it creates the myfile_SED.txt but it is 0 bytes when done. I tried to edit the file without output using this command....
But when I run the command, and check the file after compete, I don't see any changes. Can someone help me figure out why sed is not making the replacements?
Thanks,
jos.

I'm not sure if the problem I'm seeing is an artifact of sed or simply a beginner's mistake. Here's the problem: I want to add a zero-width space following each underscore between XML tags. For example, if I had the following xml:
