Formatting text with sed using iTerm2

by pmdulaney / April 14, 2013 8:23 AM PDT

In order to make the results of my sed filtering more visible, I would like, when I replace OLD with NEW to underline NEW. I'm using the tcsh shell. So, what I want is something like:

cat file | sed 's/OLD/NEW/g' | more

but I want NEW to be underlined. If you have an answer please give sufficient detail; i.e., please do not assume I know anything but basic sed. Thanks.

Ascii text?

I've never seen underlining in an Ascii text file. You may have to reveal more.

Well, I'm not sure if it's considered ASCII or not, but iTerm2 can display bolded and underlined text. I would actually want to create two versions of my sed script: one (without the underline feature I'm seeking here) for writing to a new file, and another for viewing with more on the terminal where I could just easily tell what's changed.

I see a forum just for iTerm2 at link.

I'm just an old programmer and a text file is, in my definition "ASCII" and as such has no underline. Now there are editors that will underline when they display web links and such but this is not in the source file but in some rules file.
