Terminal Colors

There exists common confusion about terminal colors. This is what we have right now:

Plain ASCII
ANSI escape codes: 16 color codes with bold/italic and background
256 color palette: 216 colors + 16 ANSI + 24 gray (colors are 24-bit)
24-bit true color: "888" colors (aka 16 milion)

Usage

(Create a symlink pytest for py.test)

pytest [options] [file_or_dir] [file_or_dir] ...

Disclaimer: I'm not the original author of this sheet, but can't recall where I found it. If you know the author, please let me know so I give the attribution.

Note: Since this seems to be helpful to some people, I formatted it to improve readability of the original. Also, note that this is from 2016, many things may have changed, and I don't use macOS anymore, so I probably can't help in case of questions, but maybe someone else can.

Mac Network Commands Cheat Sheet

After writing up the presentation for MacSysAdmin in Sweden, I decided to go ahead and throw these into a quick cheat sheet for anyone who’d like to have them all in one place. Good luck out there, and stay salty.
