I'm in the process of cracking my own WEP encrypted wireless network utilizing a 2015 Macbook pro operating on Yosemite with aircrack-ng installed. I have been following a, slightly, dated tutorial and everything has been going well up to the point of: /usr/local/Cellar/aircrack-ng/1.1/bin/aircrack-ng -a 1 -b be:ee:f0:49:94:89 /tmp/*.cap Upon which I type this in, with my corresponding .cap file, and nothing happens. It just hangs in terminal. I suspect the issue is with /aircrack-ng/1.1/, for I do not have version 1.1 installed on ports. I have version 1.2 rc-1. The problem is I don't know how to navigate in terminal to /usr/local/cellar/aircrack-ng/ to see what exactly I need to type in to make the command run. So my question is pretty simple, how do I navigate in terminal to open this folder to see the contents? In a word, how do I get to that folder in order to 'ls -l'? cd /usr/local/cellar/aircrack-ng/ did not work. Thank you in advance.
