NextCloud Talk Bot Custom Commands

Offical nextcloud documentation

The Talk add-on allows returning information when the user invokes a command preceded with a forward-slash. I have created 3 custom commands that help NextCloud admins know certain server information that would otherwise have to come from other tools ie: monitoring/graphing software:

1. Disk space used, available, and percent used via df utility
2. Latency related info via common ping utility (install if not exists for you, normally net-utils pkg or similar)
3. Listing server-side mounts via standard mount command

visualblind

#!/usr/bin/env bash

BIN_DF=$(which "df")
if ! [ -x "$BIN_DF" ]; then
  echo "df (coreutils package) not installed."
  echo "See the official documentation for more information"
  exit 1
fi

case "$1" in
