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.

How do I remember what the command even is? Like how would I discover the grep tool without using the Internet?
Discovering tools is not what the question and solution presented here was. But for that question, I recommend downloading a book about Linux as a reference or something like that. Or a basic tutorial series to read and remember basics about Linux.
You can also just list the
ls /usr/bin
directory to see what programs are there.There is actually a command to search the man pages for terms, to list the commands:
apropos
Note: I cut some parts out in the output to make it shorter. The option
-s 1
means, it will list man pages from section 1 only.
