I want to do a search in a log file like this:
/logs/loggy.log:
INFO: cats are people
DEBUG: one doth fig're and therefore one doth be
INFO: cookies made via the catapultation of figs at an acceleration of 1 m/s^2.
INFO: informative information about my information systems
I want just the 3rd line. So I command:
grep 'cat.*fig' /logs/loggy.log
But it's a large file! Let's make it faster
grep -F -e cat -e fig /logs/loggy.log
0ops. Now I'm getting back all the lines because it now matches for either 'cat' or 'fig'. I want it to match only lines containing bolth. Is there a way to do this without going back into regular expressions land?
