So I have a log.txt files which I can search in Notepad++ on Windows, however due to the sheer number of them, I'd like to be able to run grep on them. However, the data is formatted with non-rendering characters which I don't know how to include in my grep. Notepad++ shows them as the black RS. The format of the data is like
[RS]value1[RS]value2 and I need to be able to grep for value1 AND value2. This format is always constant throughout these files.
How can I make grep search for this? Is there some form of escape sequence I can use? Or should I just make it search for
value2 and completely ignore the presence of this non-rendering character?
