Stop using the grep command — this modern Linux command is smarter and faster

If you've spent any time using the Linux terminal, you've probably used the grep command. It's what you use to quickly find a search term in a file or find all the files containing that term. It's useful, reliable, and fundamental to most terminal workflows. That said, grep is old — more than 50 years old. A lot has changed since then — our computing habits have evolved, and new technologies have emerged.
