Have you ever wanted to learn “scripting” in Linux? Making them is easier than you might think. Sometimes scripts (often referred to as shell or bash scripts) are real programs with complicated code inside. Other times they’re just a long list of tasks that users put together to make getting things done under Linux faster and easier. In this article we’ve decided to make a quick guide explaining how to make a basic shell script under Linux. This tutorial won’t turn you into a or scripting expert.

Instead, it will show you how easy it is to get started (and the best practices) scripting in Linux. Why would you make a script?

Making scripts in Linux is a very useful skill to have. Even if you don’t fully understand Bash, you can use your limited knowledge of the terminal to automate and “mass-accomplish” some tasks, or simply to. For example: maybe you just built Arch Linux from scratch. The operating system is installed, along with all of the basic packages, and it can boot to the terminal when the operating system starts up. Arch Linux takes time to set up, so the process isn’t completed. It is at this point where the user could write a Bash script and accomplish everything at once.

None of this is programming, or advanced for that matter. However, given the fact that the user understands enough about the way Arch Linux works, they’d be able to automate almost the entire post-setup process (desktop environment, drivers, user setup, etc.). The only limit to your bash script is your own Linux and Bash knowledge! Making them is easier than you might think. Getting started – Shebangs When writing code, things need to be specified and resources loaded.

When scripting with the shell, some things need to be specified as well. In bash scripting this is known as a “shebang.” The shebangs used in scripts tells the script what interpreter it should execute under.

This could be Bash or any other scripts available in your system. Do note that different languages have their own shebangs. For example: When writing a Python script, the shebang would be #!/usr/bin/python, etc.

Bash has many different shebangs that can be used, but most users have probably only seen the #!/bin/bash one. As a general rule, use #!/bin/bash when writing a simple script and don’t plan on taking it off of Linux. All modern Linux distributions are on the same version of bash, and the bash shell is usually located in the same place. Another shebang that proves itself useful is the #!/usr/bin/env bash shebang. This one is designed for portability and should be used if the script is designed to run on other Unix-like operating systems (BSDs, macOS, etc.). Best Practices Writing scripts in Bash can be a complicated process if the writer makes it that way. More often than not, scripts are just a collection of different operations.

Moving a file, downloading something, installing programs, and that sort of thing. Keep in mind that Bash is a language that is designed to manipulate files and processes on the system. If Bash meets your needs, that is good.

However, do understand that for advanced programming, Bash really isn’t the right choice, and it’d be best to move onto something like Python. Make your scripts “SH” compatible and in the “.sh” format if the plan is to use scripts on more than just a Linux platform. Though other UNIX-like operating systems may have “bash-like” shells, some don’t have bash at all, and it’s good to be prepared for this. Learn the Bash shell and how it works. It’ll help you write your scripts better.

Always use a shebang and more importantly: use the right one. It can mean the difference between a good script and a terrible one that doesn’t work right. Always comment out every operation. In six months you might come back to your script and wonder what everything means, so it is crucial that your script is documented well and easy to understand (for you and anyone else who might see it). Make your code readable. Even if your script isn’t anything complex, it should still make sense, and making them is easier than you might think. Test your script for errors before giving it out to others.

Don’t make others bug test for you. Ideally, scripts should work before you send them out for people to use. Making a script To start scripting, all you need is a text editor. Any simple text editor will do – it doesn’t have to be a complicated or comprehensive one. For this example we’ll make a simple Ubuntu update script using Gedit. Sudo bash myscript.sh.

File Extensions There isn’t a difference in file extensions for scripts. Naming a file with the “.sh” file extension does little to affect the way the “program” runs. A Bash script will still run with no file extension – blank text files and everything in between as long as the right commands and arguments are present.

Even though the Bash shell ignores file extensions, that doesn’t mean the script writer should. Some desktop environments that allow for setting shell scripts to run at startup depend on the script to have the correct “.sh” file extension.

This also helps for organization purposes, too. When it comes down to it, most shell scripts are saved as “.sh” files for portability. The “sh” doesn’t have anything to do with Bash itself, and the script can run with any compatible shell. Alternatively, scripts can be saved as.bash,.ksh (Unix korn shell), etc. These file extensions are inferior and really limit the usefulness of a script.

This is due to the fact that they are designed only for the shells that use those extensions. Code resources For those looking for useful Bash scripts, check out the on Reddit. It is a collection of neat and useful scripts that are free to use and modify! Additionally, those looking to learn the advanced nature of Bash and programming with the shell should check out. The website has an entire lesson guide that teaches everything there is to know about advanced Bash scripting. If you have #!/bin/bash as first line, you can as well name the file with the extention.bash, as it will run bash. If you want to make a general standard Bourne Shell program, then use #!/bin/sh as first line.

Then you (hopefully) have a standard Bourne Shell program. You might want to show how to run script without executing anything. Useful for debugging. Also writing out messages with echo(1) would be useful for debugging. Except for that, a nice blog post about starting to use shell skript.

All set to play with Python? Python IDE is the first thing you need to get started with python programming. There are many IDEs available out there in the wild and selecting one can be a daunting task. You can get started with Python programming in a basic text editor like notepad or choose to go ahead with a complete and feature rich Python IDE like PyCharm, Pydev, Emacs or Eric. Selection of the right editor can greatly influence productivity and effectiveness of Python programming.

Professional programmers invest time well in advance and go for the IDE that best meets their requirements. Which one should you go for? This is something that you have to decide and totally depends on what you like, need, and can afford. You might need to try a few before narrowing down to the final one.

Most of these IDEs are supported on multiple platforms including Windows, Mac and Linux and are available free of cost. If you are a student planning to learn Python, I recommend freely available IDEs like Pydev with Eclipse, IEP, Emacs, PTVS or VIM. ' Course not to be missed (have a look for sure, 80% discount) -.
