Why you need the command line. How many reasons can I come up with before breakfast?

1. The Command Line makes Linux tutorials easy.
When a tutorial gives you instructions in line commands, you don't have to learn the commands. You don't have to understand the commands. You don't even have to type the commands! All you really have to do is copy the commands and paste them into the terminal window. That's easier than instuctions that have to give you a road map on how to find the button.

2.The Command Line is fun.
This one is pretty counterinuitive, but the command line allows you to take a creative approach to problem solving that is enjoyable.

3. Conversely, the Command Line allows you to cut a straight line through some of the most tedious, repetitive computing drudge work that you'll ever have to face.
I'm talking about organizing your files, sorting, moving, and processing large numbers of files. I used to spend hours on these tasks, and I hated it. These are what the command line excels at. You save time, but you cut down dramatically on the boredom.

4.Any command can be a script.
If you know how to use the command line, you know how to automate the command line with crude, simplistic shell scripts that most real programmers will look at with disdain, but which work anyway. And once again, you don't have to understand the commands.

A couple of years ago, I found this tutorial in my favorite Linux forum about how to process avi files into DVDs. From this, I was able to write a script that I have used to automatically process avi files into DVD images in batches of a dozen at a time. I just copy the files into the directories and start the script and let it run for a couple of days, and then burn 12 DVDs bangbangbang, all at once.

Now, here's the part that's kind of cool, even if it makes me look dumb: I don't understand the commands! I don't know how my own script works! I just copied the commands from the tutorial into a text file in a certain sequence, made it executable, and ran it. The commands in the script did whatever the hell it is they do, while I did other things. And now I have a bunch of DVDs to watch.

So easy... and so powerful!

Time for pancakes.

If I hadn't been in a hurry

I could have had a much longer list, with many more specifics.

Not necessarily a good thing. How does the last post get 300 reads, and this one less than 50? I'm willing to pander; just tell me how. My next post will be: "Why I hate Ubuntu (even though it's awesome)". That ought to get a hit or two!

  • The End of Gmane?
    In 2002, I grew annoyed with not finding the obscure technical information I was looking for, so I started Gmane, the mailing list archive. All technical discussion took place on mailing lists those days, and archiving those were, at best, spotty and with horrible web interfaces. The past few weeks, the Gmane machines (and more importantly, the company I work for, who are graciously hosting the servers) have been the target of a number of distributed denial of service attacks. Our upstream have been good about helping us filter out the DDoS traffic, but it’s meant serious downtime where we’ve been completely off the Internet.
  • Pwnie Express makes IoT, Android security arsenal open source
    Pwnie Express has given the keys to software used to secure the Internet of Things (IoT) and Android software to the open-source community. The Internet of Things (IoT), the emergence of devices ranging from lighting to fridges and embedded systems which are connected to the web, has paved an avenue for cyberattackers to exploit.
  • The Software Supply Chain Is Bedeviled by Bad Open-Source Code [Ed: again, trace this back to FUD firms like Sonatype in this case]
    Open-source components play a key role in the software supply chain. By reducing the amount of code that development organizations need to write, open source enables companies to deliver software more efficiently — but not without significant risks, including defective and outdated components and security vulnerabilities.

    In a blog post, Jeff Vander Stoep of the mobile operating system's security team said that in the next build of the OS, named Nougat, Google is going to be addressing two key areas of the Linux kernel that reside at the heart of most of the world's smartphones: memory protection and reducing areas available for attack by hackers.

Chew on this: Ubuntu Core Linux comes to the uCRobotics Bubblegum-96 board

Linux and other open source software have been in the news quite a bit lately. As more and more people are seeing, closed source is not the only way to make money. A company like Red Hat, for instance, is able to be profitable while focusing its business on open source. Ubuntu is one of the most popular Linux-based operating systems, and it is not hard to see why. Not only is it easy to use and adaptable to much hardware (such as SoC boards), but there is a ton of free support online from the Ubuntu user community too. Today, Canonical announces a special Ubuntu Core image for the uCRobotics Bubblegum-96 board. Read more
