Install imgo via shell script Source: https://github.com/imgo/imgo

install_imgo.sh

#!/bin/bash

## storing current dir
pushd . > /dev/null

### Installing needed packages
sudo apt-get install advancecomp libimage-exiftool-perl imagemagick \
    optipng libjpeg-progs gifsicle pngnq \
    tar unzip libpng-dev git

### Installing additional software
mkdir /tmp/imgo-installation/bin -p
cd /tmp/imgo-installation

### I reccomend to launch commands above manually! One by one. It could be very-very sad bad because you can catch some errors. Use it at your own risk!
