If you’ve ever used a Linux operating system, you may have heard of bash. It’s a Unix shell that reads and executes various commands.<\/p>
When you need to run several bash commands, you don’t have to execute them manually one at a time. Instead, it’s possible to create a script file that contains bash functions to run those commands.<\/p>
It may sound complicated, but by learning its basics, you will understand the bash scripting language and find out how it can help your workflow.<\/p>
This article will cover the process of bash scripting. We’ll go over everything from bash commands to running a bash program on a Linux terminal.<\/p>
Bash, short for Bourne-Again Shell<\/strong>, is a Unix shell and a command language interpreter. It reads shell commands and interacts with the operating system to execute them.<\/p> To fully understand bash shell scripting, you need to know two concepts – shell<\/strong> and scripting<\/strong>.<\/p> Shell is a macro processor that uses commands to interact with the operating system. This means that it can retrieve, process, and store information on a computer.<\/p> Meanwhile, scripting is the process of compiling shell commands into a new file using a text editor.<\/p> When you write bash in a text editor, you’re compiling bash commands<\/strong> or bash functions<\/strong> – a set of commands that can be called numerous times by only using the function name. The text is then saved as an executable bash script<\/strong> file with the .sh <\/strong>extension. <\/p> Bash scripts can help with your workflow as they compile many lengthy commands into a single executable script file.<\/p> For example, if you have multiple commands that you have to run at a specific time interval, you can compile a bash script instead of typing and executing the commands manually one by one. You only need to execute the script file when it’s necessary.<\/p> Here are some other advantages of using bash scripts:<\/p>Why should you use a bash script?<\/h2>
