From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

This is a good list.

There are three kinds of Linux commands:

commands I use frequently
commands I've never seen or don't know about. There's almost nothing in standard POSIX that falls in this category, and a lot of OSS that does. E.g., I use to always reach for fuser until I realized it's not a base install on many distros, so I switched to lsof which is is, and is also both more powerful and harder to use.
commands I've seen before but use so infrequently I forget they exist, or what they're called. This is sadly a larger set than I'd like.

Some of these in this list are the third kind.
