Bash Intro

This lesson is part of Bash · All levels

Summary

Bash acts as an intermediary between you and the system: it displays the prompt, reads a command line, and then executes it. The command can be an external program in the PATH or a built-in shell such as a cd. Once the command is complete, the prompt reappears and is ready to receive the next input.

Key points

Basic structure: commands [argument] [option]
Built-in shell is different from external programming
Ctrl+C cancels the running command
History displays commands on this session
