🐧 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.)
Na, ihr fleißigen Linux-Leute...
Wenn ihr irgendwann kein Bock mehr auf df -h habt, dann nehmt einfach mal dysk.
dysk ist sehr gut... und bunt.

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.

Linux tip: you can edit files from within less by pressing "v". This will launch your default editor.
If you do not have a default editor specified, you can specify one by adding the following lines to your .bashrc:
# set default editor
EDITOR=/usr/bin/vim
Substitute vim for whatever editor you prefer. (Which is obviously vim :)

A #reboot is a solution to many tech problems. But if you are on #Linux, did you know you need to reboot only if your kernel has changed? Otherwise you can do a "soft reboot" and get the same thing. You need to kill the init process and make it respawn. It varies from distro to distro but on #systemd ones, you can do systemctl soft-reboot and it'll do the job for you.
Also if you have problem with your graphical shell, you can simply restart your graphical stuff. Not even a soft reboot is needed. For instance if your display manager is lightdm like me, simply do systemctl restart lightdm.
I think this applies to other #unixlike operating systems with the similar kernel and system architecture as Linux. Maybe #BSD people can share their experience?

Linux NTFS partition invisible in Windows? It's often the partition ID. Linux might set it as 'Linux' (0x83), but Windows needs 'NTFS' (0x07). Easily change it with fdisk—no data loss. Proven fixes here. #LinuxTips #WindowsSupport #NTFS #TechFix
