do as I say

a slang saying that got popularised when Linus of Linus Tech Tips YouTube Channel did a LInux challenge, where the team tried to use Desktop Linux as their operating system, the first video was released in November 2021, in which Linus chose PopOS operating system, and there was a bug in the software center at that particular time, due to which 'steam' (the gaming software) had some conflicts with the desktop environment, due to which the installation was not being done through software center. Searching on internet, Linus resorted to command-line way, and the program warned that it may potentially damage the system, and to do proceed only if the user knows what they are doing. Linus, without reading anything, typed in the prompt which required to enter "Do as I say" to proceed, leading to the monitor going black and the system crashing.
