git emacs multfiile commit

In vanilla Emacs (without Magit), the vc (Version Control) library acts as a thin wrapper around Git. Unlike Magit, which has a specialized "staging" workflow, vanilla vc follows the standard Git logic: you must add files to the index (stage them) before you commit them.

Here are the two best ways to do this using only built-in features.

Method 1: Using Dired (Best for multiple files)

If you have many files to commit, the most efficient way is to use vc-dir (which is just Dired with version control information enabled).

  1. Open the directory: Open the folder containing your files in Dired (C-x d).
  2. Identify changes: Look for files marked with M (Modified) or A (Added/Untracked).
  3. Mark the files:

Summary of much pain trying to use bash and wireguard on a mac

Reclaiming macOS: Fixing Ancient Bash & WireGuard CLI

This guide fixes the friction between modern terminal tools and macOS's restricted system environment (Signed System Volume, GPLv3 licensing locks, and App Store sandboxing).

1. Install Modern Runtimes

Apple's /bin/bash is version 3.2 (2007). Modern scripts (like wg-quick) require Bash 4+. Install the latest via Homebrew:

brew install bash wireguard-tools

2. Fix the "Moving Cursor" Delete Key (Ghostty/Terminfo)

Newer terminals like Ghostty use definitions that root doesn't know, causing the Delete key to move the cursor forward. Compile the terminfo for the root user:
