Free online Linux course.

I think if you want a Cert that's worth having, you're going to have to pay for the exam at least.
Perhaps you could explain why you want this?

There are certainly plenty of tutorials that would likely be of more practical use than a short course eg

Larry,

listen to Chrism01, certifications are not GENERALLY the way to go. If your purpose is for a job requirement then it is understandable. If you think because you have a cert then you know what you are talking about or that it gives you credibility....DONT DO IT!

I have worked for one of the large telecomm companies for over 10 years and I use UNIX all day long. I did not get the job by being proficient at every aspect of Solaris, but what I did know was foundational and the hiring manager saw that given time I would become proficient.....but there is not a day I do not learn something.

Just a few things to get you started.

1. Learn the file system structure and how to navigate in and out of it; cd ~; cd ../;
   Learn how to make directories and files
   Learn a text editor; vi, emacs, nano, etc.
   Learn how to open files; vi file; cat file; zcat file, etc
   Learn how to retrieve info from files; cat file | cut -d'|' -f4 | sort -u | pg
   Once you get the above done, dig into the utilities and man pages
   Then, learn how to write sh, ksh, csh, etc.

This is not an exhaustive list and many people might differ on which items are most important, but it gives you a starting point. Don't get discouraged and don't get overwhelmed. My Grandfather once told me, "the only way to eat an entire elephant is one fork full at a time". Believe me there is a lot of info to learn.

Best of luck to you.

The chances of finding a free training course that results in a credible certification in any endeavour is extremely remote. Be it a driving school, language course, art course, anything. An in-depth training course requires a considerable investment of time by the people offering it. There are not many people with sufficient time to go through so much effort without wanting, or needing, monetary compensation. Linux is no different than anything else. Most Linux systems are free of charge, but a free certification course with any value will require a monetary expense.

Is there such a thing as a Linux "certification"? If there is, I would think it very rare. I know Microsoft is big on that in the corporate world, but I can't say I've ever met, or even heard of, a Linux certified person in my 33 years of programming. Most all of my time has been being Linux, Solaris, HPUX, SunOS, SystemV, etc. - none of those have certifications, at least not any you see in a corporate environment regularly. Personally, I've never seen ANY.

Red Hat has certifications. I know several RHCE's in my company, and I'm an RHCSA.

Also you can get Linux Professional Institute Certification (LPIC). I want to get some of the LPIC certs but unfortunately my job no longer deals with servers so I can't get them to pay for my training anymore.

Solaris also provides Certs; just a different name under Oracle.

Hi and welcome to LQ!
Free resources/tutorial, google/duckduckgo is the answer
But if you want a certification utilizable on the international labour market then you have to pay for the exam.
