no-env | Keep .env files out of your git history

This package includes a pre-commit hook and an installer script. Once installed, the hook executes before you make a git commit; it parses the staging area for any .env files. If a .env file is found, the commit will be aborted and you'll be notified.

At this point, you may want to include the .env file(s) in your .gitignore. If you wish to commit the file(s) anyway, you can bypass the hook with git commit --no-verify or you can set the option git config hooks.allowenv true - the script will then ignore .env files until set to false.

Instructions:

1. Download the hook & installer to your repository root: curl -O "https://raw.githubusercontent.com/exbotanical/shcripts/master/hooks/no-env/{no-env.sh,installer}"
2. Add execute permissions to the installer: chmod u+rx installer
3. Execute the installer: ./installer
