Bash Environment

Bash is a programing language.

• Bash is an sh-compatible shell that allows us to run complex commands and perform different tasks from a terminal window.

• we can directly run our command in terminal or save in file with .sh and then run it.

Terminal

Environment Variable

• When opening a terminal window, a new Bash process, which has its own environment variables, is initialized.

• These variables are a form of global storage for various settings inherited by any applications that are run during that terminal session.

• One of the most commonly-referenced environment variables is PATH, which is a colon-separated list of directory paths that Bash will search through whenever a command is run without a full path.
