`diskutil` is great but it's a travesty what they did to Disk Utility.app. It never really got any love after the APFS transition and there are things it straight up fails to do the `diskutil` command doesn't. Before they re-designed the interface, it was such a rock-solid tool that even if it failed during some task, would typically tell you why. Now it's a baby LEGO Duplo interface meant for nothing more than reformatting a flash drive.
