Setup Proxmox NTFY Notifications with CLI

Mon, 23 Mar 2026 20:39:10 +0200

This tip is largely a copy-paste of my README on the Proxmox setup in my homelab.

You can achieve the same setup using the Proxmox Web-UI, but I prefer to use CLI because it’s repeatable, extendable, and scalable. If I ever needed to change the NTFY setup, I just need to re-run the commands and I’m done.

Proxmox has a pretty nice API that we can access with the pvesh command. For example, the documentation for the notification endpoint is here.

Chain Output of Linux Commands

I needed to split a csv file on a remote server into several sections every so row.

I can use head -10 file.csv > file10.csv to output the first 10 rows into a separate file, but what about rows 10 to 20, while keeping the header?

Turns out the command is:

{ head -1 file.csv; sed -n 10,20p file.csv } > file20.csv

You can chain the output of several command by embracing them with curly braces.
