Event description


Please note: Tuesday classes are held in the Classroom. Saturday classes are held in the Meeting Room.

The command line is a tool for typing computer commands, instead of clicking menus or buttons.

Learning the command line is a great way to get familiar with core concepts of programming. Students will learn the basic parts of a command, listing, linking, tab completion, file system structure, and more, for the Linux command line.

Recommended Prerequisites: You should be comfortable with computers to take this class.


Class Category: Programming
