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.

I doubt anyone has ever regretted spending some time familiarizing themselves with the POSIX, util-linux, and GNU coreutils commands. You can do a lot by just piping these (mostly) simple tools together.
Is
awkthe best POSIX-compliantcolumnemulator?I would say sed.
Something else, all of the GNU coreutils have their own
info [command]terminal command, and often the info page is incredibly easy to read, full of example pages and highly granular descriptions of flags, error messages, and the like.Yeah GNU’s
infopages are often more detailed than themanpages.
