UNIX Basics

OS X is built upon the UNIX Darwin kernel. Having a fundamental understanding of working the UNIX operating system can give you a great advantage of troubleshooting, tuning and general administration of your system. I have worked in many flavors of UNIX in the past 10 years which include SunOS, Solaris, IRIX, HP-UX, AIX, RedHat Linux, SUSE Linux and of course OS X. Each type of UNIX has its own uniqueness, different commands to manage system resources, etc. However, for the most part there is a lot of similarities among all these versions of UNIX. I wanted to list at least a couple of commands that may help you.
