Tbh you could also just set up sshd.
It’s turtles all the way down
I mean it’s good practice generally just in case, even when it’s not needed it makes it more maintainable
I usually go with YAGNI but shell quoting can get to be a pain so I try to do it right in scripts or aliases
But for a single one-off invocation lol definitely not quoting echo args
Save yourself. It’s not too late to preserve your ignorance.
