Bash scripting is a really valueable skill, and necessary if you plan on, or are working in IT.
Why is it so usefull?
From starting a Polybar on Arch Linux with a Bash script, to getting information from thousands of servers at the press of a command, Bash scripting can do it all (well quite a lot).
To be more clear thought, server managing for example is a lot better with Bash scripting. I'll show some examples!
#!/bin/bash echo Hello world!
This is a simple script which prints
Hello world! in your terminal. Let's break it down!
is a shebang. This indicates that the script is in fact a Bash script.
echo Hello world!
Runs the command
echo with the parameters
Hello world!. Echo prints out a text.
Congratulations! You've made your first Bash script! I recommendend trying to make something such as a simple fetch by your own using help from the internet, to learn the depths of Bash scripting.
