Terminal is a very powerful application. Every Computer Science Student Should know the Terminal Commands and how the work.
Terminal (also referred to as Terminal.app) is a terminal emulator included in Apple’s OS X operating system. It originated in OS X’s predecessors, NeXTSTEP and OPENSTEP, and allows the user to interact with the computer through a command line interface. It provides an environment for Unix shells, which, among other things, allow the OS X user to visually interact with the system core. Terminal features include tabs and customization of styles such as fonts and colors.
Command-line access to UNIX.
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.
