🐧 Linux Command of the Day: jq
Master parsing JSON data directly from the command line! Ideal for processing API responses, config files, or logs. A must-have for scripting & automation. #LinuxTips #DevOps #Automation
Key flags: . (identity), keys, select(), | (pipe)
Examples:
echo '{"n":"L"}'|jq .n
echo '[{"s":"ok"},{"s":"err"}]' | jq '.[]|select(.s=="ok")'
echo '{"u":"a","l":"h"}'|jq keys
So what happens if you set up a laptop to be a server and you close the lid? The system goes to sleep.
This is not fantastic behavior for a server, so to fix it, we have to edit
/etc/systemd/logind.conf
and add the following lines:
HandleLidSwitch=ignore
HandleLidSwitchExternalPower=ignore
HandleLidSwitchDocked=ignore
Reboot. Now the laptop won't sleep when the lid is closed.
(Obviously, this is only for systemd systems. Other init systems need a different method.)

Forget to use sudo? Don't retype everything: sudo !!
It reruns your last command as root. Saved me more times than I can count!
So we all have used Windows, right. I have a Digital license for both that are tied to my account. But we all have paid for it and I'm sick of the choices that Microsoft has made. Microsoft: "Yeah let's bake in Ads and USELESS AI in the product our users pay for"
yeah I won't be using that. I still love Windows deep down, but that's Windows 10. Too bad it's not getting supported unless you pay for ESU. I'm gonna use Linux on PCs in the future.
In my opinion: Fuck Microsoft and Win11.
