OS X is built on an industry-standard UNIX foundation. The Terminal application allows you to access the complete UNIX environment using standard commands, tools, and scripting languages. Terminal includes numerous shortcuts that will save you time. For example, you can copy and paste text commands, and if you drag files or folders into Terminal, the correct file path appears on the command line. You can customize Terminal with your favorite fonts and background colors, including transparent, as well as manage multiple sessions from a single window using tabs.
