You’re probably wanting [ -z "${VAR1}" -a -z "${VAR2}" ]. Note in bash that there are minor differences in how [ ] and [[ ]] tests are handled. You can pull up a handy cheat sheet of the operands on most distros by running man test, though you’ll need to read through the CONDITIONAL EXPRESSIONS section of man bash if you want to see the minor differences of the single vs double square bracket commands (mostly whether locale applies to string order, as well as whether operands are evaluated in numeric comparisons).

While I agree in general, that wouldn’t have helped in this case, and likely would have just made things worse. He couldn’t draw on the Karen for being a racist piece of trash, and his next interaction was with the police, whom he certainly couldn’t have drawn on. Then the cops would have trumped up the charges because he was armed, and he never would have seen the gun again after it disappeared into the evidence locker.

All legit. At the end of the day, both the commands that go through systemd and the direct cat something >/proc/… or cat something >/sys/… are all doing the same thing - telling the kernel to do some procedure.

There’s some settings stuff in /proc and /sys that you don’t want to tweak without knowing the effects, as they could break things in hard to fix ways, but for stuff like beeping or changing sleep states, the worst you’ll do is lock up your computer and need to reboot. And even that is rare unless the hardware really doesn’t like a particular sleep state.

Except we’re talking about Texas, where Democrats have never held enough power to do any significant gerrymandering. Assuming you’re acting in good faith and not just a bot, is it possible that you’re failing into the trap of assuming that because one of the most heavily gerrymandered districts (Texas 35th) is blue that Democrats did the gerrymandering?

They didn’t. Republicans did, to pack as many blue votes into a single district as possible so multiple others around it could be red. If the districts were drawn fairly, the thin corridor connecting Austin and San Antonio would be red, and multiple districts above and below that corridor would be blue.
