I have some parameters for some Linux commands which are burned in my brain, and work for 95% of my needs:
* tar czvpf (also x)
* rsync -PSavv
* netstat -lntp (also works for ss)
I got used to those way back when during my Service Desk times, and now they're just muscle memory.
Oh. And the one more "modern" is:
* kubectl get events -Aw (btw: "alias k=kubectl")
That's my Kubernetes variation of "journalctl -f" (also previously known as "tail -f /var/log/messages").
How about you? What are yours? 馃槃
