Is there a good place to practice Bash commands daily?

Try the Bash track on Exercism. You can work on exercises on your own machine and submit them from there, so you get practice in your usual shell environment.

Many of the exercises are also available in other languages, which makes it useful if you want to compare approaches. It’s worth checking whether the available exercises match the kind of command practice you want.

Killercoda has a lot of free scenarios worth browsing. They’re scenario-based rather than necessarily a daily set of short Bash problems, but they could give you more hands-on terminal practice.

FreeCodeCamp is another option, though its shell material is mostly aimed at the basics. It may be useful for filling gaps, but it might not have the volume or difficulty you’re after for daily practice.

SadServers is worth a look if you’re open to troubleshooting scenarios, but that’s a different kind of practice from focused Bash exercises. More complex, programming-oriented scenarios were suggested, though there’s no guarantee they’ll be added.
