If you want to perform a task against each item in a set, for loops are a good way to do that. But how do you set these up? How can you leverage looping in a Bash script? What is the meaning of life? Well, LearnLinuxTV can’t help you figure out that last point, but with this video you’ll absolutely learn all about for loops!
The word “Universal” can refer to good or a bad thing. Universal is working on another Jurassic Park sequel? Probably a bad thing. A universal script to help you consolidate tasks on the Linux commandline? Definitely a GOOD thing! In this video, you’ll see an example of creating a “universal update script” to help you deal with using multiple distributions.
Looping isn’t just something you do in an unknown city while driving with a broken GPS – looping is a very important concept in programming and scripting languages. And that’s what we’ll go over in this episode of this bash scripting series. Specifically while loops, which allow you to continually execute something as long as some sort of condition is met. In this video, you’ll learn all about this so why not just give that play button a click and start learning?
How do you tell whether or not a task completed successfully? Usually, an error message is a sure sign that something went wrong. But when it comes to Linux, you won’t always have that to rely on. In this video, you’ll learn all about exit codes, which is how you determine whether or not a task in Linux is successful or if it failed.
There are a lot of “Ifs” in life. “If” you’ll get the job, “If” you win the lottery, “If” only you knew the answer to all things. But there’s no “Ifs” about it, you’ll learn all about If Statements in Bash with this video. We’ll go through how to set up an if statement, why you’d want to write one in the first place, and some additional bash-related shenanigans!
Bash has all kinds of very useful concepts and there’s a seemingly endless amount of things to learn. So here’s a super easy video for you, all about basic math. Performing math operations in Bash is a bit different than on other platforms, so it may prevent some future confusion if you learn about these things now. And why not? This tutorial is only six minutes long and there’s plenty of worse things you can spend your time on, so check out this Bash tutorial and learn how to perform basic math functions!
