I haven't used OS X since an awful experience with its commandline tools and CD Xcode about 2009, that time getting rid of all Apple stuff but coming back after iPhone/iPad/FaceTime/iCloud/etc. Now I am wondering whether I could solve this problem other way, I love to use tools such as awk, mogrify, imagemagick, etc -- they are pretty integral part of me because I don't like to relearn things. Most of the time, I solve problems with short one-liners so if I cannot do it, my productivity will drop a lot.
So could I run *ix Commandline tools on Macbook Air? I have an old laptop in the same WIFI network so I may be able to connect it for remote control?
