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 80% of my usage of awk and sed:

"ugh, I need the 4th column of this print out": command | awk '{print $4}'

Useful for getting pids out of a ps command you applied a bunch of greps to.

”hm, if I change all 'this' to 'that' in the print out, I get what I want": command | sed "s/this/that/g"

Useful for a lot of things, like "I need to change the urls in this to that" or whatever.

Basically the rest I have to look up.

I say that covers around 99% of the awk/sed I use.

I was gonna write 99%, but then I remember I also need capture groups quite often. That would make 99% I'd say
