Linux Command Every Engineer Should Use!

Let's say you're searching the whole file system for log files, but you're just a regular user, not the root user. So, you run this find command, but all of these permission denied errors are ruining your day. There are more errors than actual found log files. You have to look through all that garbage to find what you need. There's an easy fix. You can just throw these errors away. Just tell your bash shell to dump them into the Linux black hole. And that black hole is {slash} dev {slash} null. At the end of your previous command, you simply add this. And bam, clean result. Just log files shown, no more errors. The magic happens in that part of the command. Two symbolizes errors. The greater than symbol tells bash to redirect these errors. {slash} dev {slash} null is the location where errors should be redirected. And since {slash} dev {slash} null doesn't care what it receives, it just throws that content away. So, you get no more errors on your screen. They are sent into the void that is {slash} dev {slash} null. Now you can get rid of any errors you don't need and get that clean output.
