Can you share pics with this door? How do you walk outside and have it lock behind you?

Thanks for sharing! The band poster is particularly very cool :)

I wonder if someone would go so far as to put tags on each of their record albums to do the same thing (kind of odd not actually playing the vinyl, but it’d be easier to play an album!)

Not an answer: whats your setup for your cameras/security?

Ooh, Ive heard of these. Can you name some of the ways you use them? Do these effectively work as a cheap alternative to a physical switch or can they be used more creatively?

Actually cd isnt a program. Your present working directory is managed entirely by the shell. If you type “type cat” in the terminal it will tell you its a program, but “type cd” says its a shell builtin. So yes, cd depends on the shell and zsh has some awesome quality of life features. This is not something you can do in bash.
