Get a robotic avatar of your environment variables setup

robothash-env.sh

#!/usr/bin/env bash

# This simple line lists your environment variables,
# hashes them into a SHA-1 and uses that to query a "unique"
# robotic avatar from robohash.org.
#
# This lets you see quickly if something is out of place in
# a server configuration, as any slight change of the config
# will result in a totally different image, which is easier
# to catch at a glimpse than remembering checksums.

# On macOS:
echo "https://robohash.org/$(printenv | shasum | base64).png"

# On *nix:
echo "https://robohash.org/$(printenv | sha1sum | base64).png"
