100 Days of Coreutils

I consider myself an advanced Linux and macOS user. I&rsquo;m currently a software engineer developing primarily for Linux systems, and I&rsquo;ve previously worked as a Linux and Mac System Administrator. Over the years I&rsquo;ve spent tons of time on the command line, however I bet there are a bunch of GNU Core Utilities (coreutils) commands I&rsquo;ve never used before.
