What is stdout, stderr, /dev/null and redirection? | #4 Practical Bash

Показать описание

Surely you've heard other talk about stderr or "Standard Error". Similarly there is "stdout" or "Standard Out". But what do they mean. What are those numbers and what is redirection? Ever heard of /dev/null? This video is all about the different output streams in bash and how you can manipulate them to your advantage

That terminal emulator palette is beautiful. Powerlevel makes it extra sophisticated.

I really liked your theme. Can you make a video about it?

Why is echo "the current version of foo is $(get_latest_version 2>&1 1>/dev/null)" print out "Resolving Host" etc instead of nothing? Isn't that they are redirected to stderr inside the function by 1>&2 and then they are redirected to stdout and discarded by 2>&1 1>/dev/null? or I am getting the order wrong here? Thanks

Hi. Why redirecting 2>&1 if stream 2 is echoed on the screen anyway?

when you say /dev/null at 3:09 you sound like Gru from despicable me

Can you please link to your vim/powerline/bash configs, they look pretty neat 🤩

Hi, why does the echo command of your script (that outputs the function) isn’t the first thing echoed to screen even if functions body redirects to stream 2?

i think this video should've come after you explained curl
