Twenty years ago, when I first started using Linux, finding a distribution that worked, out of the box, was an impossible feat. Not only did the installation take some serious mental acuity, configuring the software and getting connected to the Internet was often a challenge users were reluctant to attempt.

But, even among those distros that “just work,” some rise to the top to stand as the best in breed.

Around this time every year, our minds turn to copyright. Or maybe they turn more to copyright. After all, open source works because of copyright law. As you may already know, copyright laws give the authors of works the exclusive right to copy (among other things) their work. These rights attach as soon as the work is fixed in a tangible medium (written down, saved to disk, etc.). So the rights that open source licenses grant rely on copyright law. read more

Most of the Linux commands you encounter do not depend on other operations for users to unlock their full potential, but there exists a small subset of command line tool which you can say are useless when used independently, but become a must-have or must-know when used with other command line operations.
