Send Your Linux Errors Into the Void!
Search the whole filesystem for log files as a regular user and the screen fills with permission denied errors, more noise than actual results. This one shows the tiny thing you add to the end of any command to make all that noise disappear.
You'll learn where errors go by default, why the number 2 stands for the error channel, how a single redirect points them somewhere else, and why /dev/null throws away everything you send it.
We break it down in under a minute.
