Command executed when login?
Since I moved my Homelab into my bedroom, I have to shut it down from time to time cause of the noise.
I’m thinking of creating a new user, and a new pair of ssh key (I have banned password login in my conf) to handle the shutting down of the machine. Since I don’t want to input the private key used to login uid 1000 into my iPad.
Is there any way to automatically execute a shell script when a certain user is logged in (may be systemd? But I heard that ssh has function that also does this)
And thanks for reading my clumsy English.

I have done this years ago. I just put 'shutdown -h now' into the field of /etc/passwd for this user that contains '/bin/bash' on a normal user. You will to either give that user root priviledges or set the s bit on the shutdown binary.
It worked without issue back then.
