[Solved] Multiple line search, replace second line, using awk or sed
All, I appreciate any help you can offer here as this is well beyond my grasp of awk/sed...
I have an input file similar to:
What I need to do is replace any instances of the following:
with the following:
In pseudo code terms...
If a whole line matches: &LOG Part: "@DB/TCxxxxxxxxxxx/xxx" (where the "x"s could be any character)
and the next whole line matches: &LOG
replace the "next line" (&LOG) with: &LOG Cloning_Action: RETAIN
Note there may be multiple instances needing replacement within a given file as the sample used here indicates
When run properly the above input would come out looking like (the change is highlighted in red):
Thanks in advance for any help you can offer...

Reason: resolved question
You're right, my apologies, it does work against this, which is really weird because i copy pasted it directly from the input file i am using (though it is a snippet of a larger file, it matches the pattern)...
I'll investigate a little more and see what i can find is different...

so what I've found is that the blank &LOG lines have a trailing space on them in my original file, but when i copy paste out of the forum here it does not have a trailing space... wondering if this might be the issue
Yet another update... I ran the first above response against a snippet even with a blank space and it worked... investigation continues

Thanks guys, sorry for my stupidity on the dos2unix...
