~away, the "other" body of water varies ~blackNatural gas leaching.
IT MUST LOOK LIKE:

I am trying to get a word from a line using sed. Following is the line which I want to use.
inet addr:10.245.86.15 Bcast:10.245.87.255 Mask:255.255.254.0 inet6 addr: fe80::1031:3dff:fe01:55e1/64 Scope:Link
From the above line, I need the ip address like 10.245.86.15 only.
I have a large file in which each line has three or more blank-delimited words. I'd like to code a grep to keep only those lines which have the letter M in the last word. the M (if present) will be the first character in the last word.

I have done a bunch of searches on this but the terms seem to get tangled in the more popular search of "colouring the output of grep / awk". I am trying to find a way to grep/awk through the output of a command to find text of a specific colour. The command's output has a range of colours signifying too many different things to specify using text, with colour being the only form of grouping.

So here's the question:
How can I configure grep to search recursively through all files in a directory, or if need be starting from root to find the pattern "2880" I've looked in the man page for grep and I can't see how to do it, is grep the right tool to use for this ?
I want to pipe the output of a command into grep as the search TERM, rather than the text to be searched, like this for example
Code:

I know grep can search recursively (ie through all subdirectories to the bottom of the directory tree), but is it possible to ask grep to only search say, 3 levels down? That means the current directory, any directories in the current directory, and within any directories within those?
