What is bash scripting?

The basic idea of bash scripting is to execute multiple commands to automate a specific job.

As you might know, you can run multiple commands from the shell by separating them with semi colons (;):

ls ; pwd

The previous line is a mini bash script.

The first command runs, followed by the result of the second command.

Every keyword you type in bash scripting is actually a Linux binary (program), even the if statement, or else or while loops. All are Linux executables.

You can say that the shell is the glue that binds these commands together.
