Command execution on Ansible controller from host

I prefer simple and portable shell scripts too. While I use here documents a bunch too this is the first time I've seen this idiom:

    #!/bin/sh
    tail -n +3 <current-filename> | ssh -p 1234 root@myserver_ip  ; exit
    set -eu
    ...

Clever.

When you write `install`, is this another script that you have installed on the server beforehand or is it a function/alias or something? [EDIT: Duh, didn't realize this was actually a standalone program (standard but non-POSIX AFAICT) I haven't used.]

I came up with this trick to avoid nested here documents, which would make syntax highlighting unusable.

The "install" tool is very common on almost all Unix systems. It is usually called by a Makefile on "make install", but of course can be used by anyone.

See man install: https://linux.die.net/man/1/install
