HeavyScript installation and setup for TrueNAS management.


Install HeavyScript

HeavyScript is a bash tool for automating TrueNAS Scale application management. It is recommended in the TrueCharts documentation, but is not required when using TrueCharts. Refer to the HeavyScript GitHub repository for more information.


HeavyScript is not a TrueNAS or TrueCharts application, it must be installed from terminal. Open a shell session on your server: System Settings - Shell.

Review the HeavyScript deploy script on GitHub. The HeavyScript one line installation can be completed using curl.

curl -s https://raw.githubusercontent.com/Heavybullets8/heavy_script/main/functions/deploy.sh | bash && source "$HOME/.bashrc" 2>/dev/null && source "$HOME/.zshrc" 2>/dev/null
