Network Search and replace sed or tr
Hi folks,
I need to search and replace specific text in a file and replace it. I have a text file that does not have any newlines or carriage returns. All newlines have been removed. Here is what I need to do.

Find the exact string “DH” (quotes included) and replace it with \n”DH” (basically putting a newline in front of all occurances of “DH”)

I have tried using sed...
sed 's/\<"DH"\>/\"DH"/g' DHt.txt > DH2.txt
When I tried the sed example the output has nothing in it. I think this is because there are no newlines or carriage returns.

And tr command...
tr -s '["DH"]' '[\\012"DH"]' < DHu.txt > DHt.txt
This replaces anything with DH in it and the newline is not added, it adds \012. It needs to to find only “DH”

Now I'm pretty new this type Unix commands so my syntax could easliy be wrong .

Thank all in advance,
Joaquin
