Prerequisite Installation

Debian & Debian-based Linux distributions:

1) Install manually

apt install jpegoptim optipng webp -y

curl -L -o /usr/local/bin/avif https://github.com/Kagami/go-avif/releases/download/v0.1.0/avif-linux-x64

2) Install via a script - run the script as sudo user

Script installation

Clone the repository

git clone https://github.com/rashkopetrov/img-optimize.git $HOME/.img-optimize

Install the script

Method 1 : Add an alias in .bashrc

With this method img-optimize can only be used by the current user.

echo "alias img-optimize=$HOME/.img-optimize/optimize.sh" >> $HOME/.bashrc
source $HOME/.bashrc

Method 2 : Copy the script itself to ~/.local/bin and remove the .img-optimize directory

With this method img-optimize can only be used by the current user. Only the script file is kept on your machine and not the entire GitHub repository.

cp $HOME/.img-optimize/scripts/optimize.sh $HOME/.local/bin/img-optimize
chmod +x $HOME/.local/bin/img-optimize
rm -rf $HOME/.img-optimize

Method 3 : Add an alias to the script in /usr/local/bin

With this method img-optimize can be used by all users.

sudo ln -s $HOME/.img-optimize/optimize.sh /usr/local/bin/img-optimize
sudo chmod +x /usr/local/bin/img-optimize
