### Usage
|
|
|
|
1) Download the script and make it executable
|
|
|
|
```bash
|
|
wget https://raw.githubusercontent.com/VirtuBox/wp-optimize/master/optimize.sh
|
|
chmod +x optimize.sh
|
|
```
|
|
|
|
2) Launch the script and set the path of your images as first argument
|
|
|
|
```bash
|
|
./optimize.sh /path/to/your/images
|
|
```
|
|
|
|
To avoid permissions issues, you can run the script with another user with sudo
|
|
|
|
```bash
|
|
sudo -u www-data ./optimize.sh /path/to/your/images
|
|
```
|
|
|
|
### Warning
|
|
|
|
Conversion process can take a while, you can use `tmux` to launch the script and be able to close your ssh connection without interrupting conversion. Then just use `tmux attach` to login back in your tmux session.
