Safe Remove Script for Zsh

Overview

The safe-rm.sh script is a safety tool for Unix-like systems using the Zsh shell. It overrides the standard rm (remove) command to provide additional safeguards when deleting directories, especially those that are part of a Git repository. This script helps prevent accidental deletion of repositories.

Features

• Git Repository Detection: Automatically detects if a directory is a Git repository.
• Repository Details Display: Shows the current branch and last commit message for Git repositories.
• Deletion Confirmation: Prompts for user confirmation before deleting Git repositories.
• Color-Coded Warnings: Uses colored text for better visibility of warnings and messages.

Installation

1. Download the safe-rm.sh script.
2. Add the following line to your ~/.zshrc file to source the script:

source /path/to/safe-rm.sh

3. Restart your terminal session or source your ~/.zshrc file:

source ~/.zshrc

Usage

Once installed, use the rm command as you normally would. The script will automatically invoke the safe_rm function when you attempt to remove any directory.

Example:

rm my_directory

If my_directory is a Git repository, you will see a detailed warning and be prompted for confirmation before deletion.

Note

• This script was tested only in Zsh shell but since Zsh is built on top of bash this probably works on bash too.
• It only affects directories recognized as Git repositories.
• The aliasing is effective only in the shell sessions where it's sourced.
