Installing AppImages systemlessly

#!/bin/bash

# This script shows how to create
# an AppImage .desktop file with
# its icons and necessary information.

# First of all, we will create a folder
# in /tmp for downloading and automatically
# deleting the binaries.

mkdir /tmp/appimaged
cd /tmp/appimaged

# Now, we must download the binary from
# https://github.com/AppImage/appimaged
# This daemon will monitor some folders
# and, when a new AppImage is detected,
# it is automatically installed in our
# userspace

# Check if we have "wget" installed
command -v wget >/dev/null 2>&1 || { printf >&2 "I require \"wget\" but it is not installed - install it by using:\n\t[sudo] apt install wget\nAborting\n"; exit 1; }

# Now, download the required script
wget "https://github.com/AppImage/appimaged/releases/download/continuous/appimaged-x86_64.AppImage"
chmod a+x appimaged-x86_64.AppImage

# Before starting the daemon, create
# some necessary folders
mkdir -p $HOME/Applications
mkdir -p $HOME/bin

# Notify the user about the just created folders
echo "For installing some AppImage, please copy/download/move it to $HOME/Applications or $HOME/bin - you can just leave it on the Downloads folder, but it is not recommended as it can be easily removed"

# and finally install the daemon
./appimaged-x86_64.AppImage --install

# Now, a logout is required for applying the changes
echo "Please, logout and log-in again for finishing the installation"
echo "You can now manage the daemon by using the \"appimaged\" command"
echo "Brought to you by Javinator9889"
