Linux

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 just completed my LPIC-1 journey and reached the certification!

While studying and doing tests, I took notes in markdown and summarized every concept, so I think they could be a useful "study companion" for anyone who wants to study, learn about Linux, or just read out of curiosity.

These notes are divided by topic as the original LPI path requires, and are integrated from various resources and quizzes I completed during the journey.

I'm leaving them here if anyone wants to read them or contribute in any way. I really appreciate it!
