Updating Parton

Parton includes a built-in self-update command.

Check for updates

parton update --check

This checks GitHub for the latest release and compares it to your installed version. No files are changed.

Example output:

Current version: 0.1.0
Checking for updates...
New version available: 0.2.0

Run 'parton update' to install.

If you are already on the latest version:

Current version: 0.2.0
Checking for updates...
Already up to date.

Update to the latest version

parton update

This will:

check GitHub for the latest release
detect your platform (macOS arm64, macOS x64, Linux x64)
download the correct binary
replace the current binary atomically
print the new version

Example output:

Current version: 0.1.0
Checking for updates...
New version available: 0.2.0
Downloading parton-darwin-arm64 from v0.2.0...
Installing to /usr/local/bin/parton...
✔ Updated to parton 0.2.0

Verify after update

parton version

Alternative: reinstall via script

You can also update by running the install script again:

curl -fsSL https://parton.run/install.sh | sh

Both methods produce the same result.

Supported platforms

The update command supports the same platforms as the initial install:

macOS Apple Silicon (arm64)
macOS Intel (x86_64)
Linux x64

Troubleshooting

Permission denied

If the binary is installed in a system directory (e.g. /usr/local/bin), you may need to run with elevated permissions or reinstall to a user-writable path like ~/.local/bin.

Network error

The update command requires internet access to reach GitHub. If you are behind a proxy or firewall, the download may fail. In that case, download the binary manually from https://cdn.parton.run/v{version}/parton-{platform}-{arch} and replace the existing binary.

Unsupported platform

If you see "Unsupported platform", your OS/architecture combination is not yet supported. Check the installation page for the current list.
