Running PowerShell scripts as git hooks

Since powershell 7.2 the script must have .ps1 extension on Windows. So this answer will not work.

You can embed PowerShell script directly inside the hook file. Here is an example of a pre-commit hook I’ve used:

#!/usr/bin/env pwsh

# Verify user's Git config has appropriate email address
if ($env:GIT_AUTHOR_EMAIL -notmatch '@(non\.)?acme\.com$') {
    Write-Warning "Your Git email address '$env:GIT_AUTHOR_EMAIL' is not configured correctly."
    Write-Warning "It should end with '@acme.com' or '@non.acme.com'."
    Write-Warning "Use the command: 'git config --global user.email <name@acme.com>' to set it correctly."
    exit 1
}

exit 0

This example requires PowerShell Core but as a result it will run cross-platform (assuming this file has been chmod +x on Linux/macOS).
