#!/bin/bash
id=$(grep "$1" /etc/pve/.rrd | cut -d'/' -f 2 | cut -d':' -f 1)
[[ "$id" == '' ]] && echo "The specified LXC does not exist." && exit 1
node=$(grep "^\"$id\":" /etc/pve/.vmlist | cut -d'"' -f 6)

ShareXen - Another ShareX Custom Uploader PHP Script
@Xenthys
Xenthys / img2irc.py
Created October 2, 2016 23:39 — forked from Polsaker/img2irc.py
Makes beautiful ART from regular, boring images.
#!/usr/bin/env python
# This script shall be distributed under the "who cares" license.
# Just leave this note here stating that Polsaker
# (https://github.com/Polsaker) created this.
# Usage: img2irc.py image.png [-rgb]
# With -rgb the script uses RGB to compare colors instead of L*A*B*.
# It is faster but it might lead to worse (or better ;D) image quality
