Have a good regex question needed to modify some files. Suppose you have a tab deliminated log file that you want to save only those lines which contain a particular piece of text, and delete the rest of the lines. Each new row entry is determined by a new line. So for example:

1: 2013-06-01 09:20:43 /stuff_I_want 200
2: 2013-06-01 09:20:43 /stuff_I_want 200
3: 2013-06-01 09:20:43 /stuff_I_dontwant 200
4: 2013-06-01 09:20:43 /stuff_I_want 200

So lets say I only want to keep lines 1,2,4, and delete 3. (The file doesn't have 1,2,3,4, I'm just denoting that line by line). How can I construct a regex to keep only what I want and delete all else from file? But remember, I want the ENTIRE line from the parameter of "stuff_I_want" in the regex. Thanks!
