Create and Run Linux Scripts to Run Multiple Linux Commands - Save Time Running Linux Commands
You can easily automate the process of running several Linux commands by creating and "running" a Linux script.
With a Linux script, you can take a series of routinely run Linux commands, put them in a file and then run all of them by simply typing in the name of the file and pressing Enter.
A Linux script is similar in concept to
a "macro" in a word processing program, spreadsheet program, or other software program.
Linux Commands Training Tips: Using Linux scripts to automate Linux commands is being describe here to demonstrate why you shouldn't use Linux GUI utilities (unless you absolutely have to) - and to demonstrate another one of the great benefits of learning how to use Linux commands - and to give you a "sneak preview" of how to create and run a Linux script.
In an upcoming section of this Linux commands book, you will learn much more about creating Linux scripts, creating Linux text files and using the Linux scripting programming language.
Defining and Creating a Linux Script to Automatically Process A Series of Linux Commands
A Linux "script" is a Linux text file that has been made "executable" (so that it can be run, or "executed"), in the same way as you run a Linux command.
A Linux script contains a bit of text at the top (just this: #!/bin/bash) and then one or more Linux commands that need to be run automatically.
A Linux script can also contain programming logic, such as "if .. then" statements" to determine if and when the Linux commands in the script should be run.
Linux scripts can be as basic as running a single Linux command or they can be extremely complex and include hundreds of lines of programming logic and Linux commands.
Linux Commands Training Tips: One of the great benefits of learning to use Linux commands for Linux system administration is that you can easily put Linux commands in a Linux script to automate routinely performed Linux commands.
This allows you to do routine "basic" tasks and also do very complex Linux system administration tasks - quickly and easily by simply typing in the name of a Linux script and pressing Enter.
Knowing how to create Linux scripts to automate routine Linux System Administration tasks is a highly sought-after Linux skill!

What do you need to learn about running Linux Commands - using Linux command options - working at a Linux terminal (a.k.a. terminal emulation window)?
Do you need to learn how to do Linux system administration and working with the Linux command line interface (a.k.a. Linux CLI)?
Or do you need to learn Linux command scripting and creating Linux scripts - and editing Linux system configuration text files with Linux text editors?
