Hey Apple – Where’s the stinkin’ .Profile?
Posted on March 12th, 2014 in Apple, Linux/Unix | No Comments »
So after a multi-year hiatus from living daily in the OSX world, I recently could resist the “Shinny” no longer; I broke down and purchased a MacBook Pro. Just as with every Apple product I’ve used through the years, this new rMBP 13” is a wonderful piece of hardware. But Apple’s consistently sublime hardware is not the subject of this post, but rather the software – OSX 10.9 Mavericks to be specific.
While I’ve been away form the Mac ecosystem (Snow Leopard days), many things have changed – The App Store, death of physical media, the hard drive displaying by default on the Finder’s desktop, I could go on. But one thing that has remained true as the north star is OSX’s Unix underpinnings, and where there is Unix – there is a Terminal.
As someone who’s idea of making a computer useful requires, regardless how pretty the GUI is, there is always a CMD.exe or Terminal shortcut overtly located on the desktop – you can be sure getting down to the command line on my new notebook was a top priority. With Terminal prominently situated on my dock I was ready to work – or so I thought until I started barking some of my favorite Linux/BSD commands at the window.
What the heck? No “ll” alias? And what about my other favorite behaviors? Ok, ok – surely I just need to modify the .profile (hidden file in the home folder of many *nix systems that defines the CLI’s operation.) From the command line, I issue a “ls -al” to show me the hidden “.” files, and sure enough – no “.profile” – great, I’ll just grab one of my linux ones and be good to go. Right? Wrong!
Meet the .bash_profile file
After a little bit of digging online, I found some docs referring to the .bash_profile. Interestingly, on my fresh OSX 10.9 Mavericks build this file does not exist, not even an empty one. So if you, like I, desire more customized control over your Terminal experience – feel free to create a .bash_profile and then use my template below to populate it. Consider it a soup starter, and you an mix in your favorite changes – Enjoy.
