5 Courses to Learn Shell Scripting in Linux and UNIX Online

A huge chunk of a developer's time is wasted in trying to repeat tasks and commands, especially when it comes to working with a bunch of UNIX or Linux machines and a good knowledge of shell scripting can free you from such mundane task and give time to do some interesting stuff. If you don't know what is shell scripting then let me tell you is nothing but a program written using shell built-ins and Linux commands to automate things e.g. checking if a host is reachable or finding and deleting large files which are older than certain days or archiving them into another machine. Basically, it's a tool which allows you to automate boring and repeating task and that's the way programmers should work. They should not be repeating stuff, instead should be investing that time to create a script or program which can automate that task.

Why learn shell scripting?

I always ask programmers, developers, and system admins to learn and master shell scripting because of its one of the skill which not only saves time and increases productivity but also separates yours from average programmers who don't have a passion for automation and not good with their tools.

I'll give you one of the real-world examples form my career. Once I was working on a project which had around 40 Linux hosts where our Java application was installed.

After one big release, we realized that one config change was missed and there wasn't enough time to do it a proper way i.e. to create another build and load into deployment tool (we're using Opsware that time) and release again. So, we decided to manually make the change in all 40 hosts.

I started doing changes and after 10 minutes later my tech lead came to me and ask all done? I said, well, I have just started, only two servers are done now. He looked at me with curiosity and asked how am I doing the changes?.

I told him that I am going to each box, opening the config file in VI editor and then making the change. He took the control from me, make the change in the config file and writes a script to copy that file to all 40 servers, which took just 2 minutes to him and run it another 1 minutes and all done.

I was surprised, why I didn't think about that but my lack of Linux knowledge and shell scripting prevented me.

That day I realized that if you want to improve your productivity and impress your colleague then you must be good at your tools and shell scripting is one of them.
