Script to prevent accidentally running the older version of GPG which is built into Git for Windows

gpg

#!/bin/bash

# This script prevents the version of GPG that is built
# into Git BASH for Windows from being run accidentally.
# It is for the very specific situation when, on a Windows
# machine, you have a newer version of GPG installed on
# your machine directly, and you also have Git BASH for Windows.
# In this circumstance, running the 'gpg' command from a Windows
# command line prompt will invoke the newer version of GPG installed
# directly, but invoking 'gpg' from the Git BASH terminal will
# invoke the older GPG version built into Git for Windows.
# You can force Git itself to use the newer version of Git built
# into Windows by running the following command:
#      git config --global gpg.program "c:/Program Files (x86)/GNU/GnuPG/gpg2.exe"
# However, while that command will cause Git to always use the newer
# GPG version, if you try to run a 'gpg' command from the Git BASH
# terminal directly, the older version of GPG will still run.
# Since the older version and the newer version store the keys
# in different locations, this can cause confusion. If you need to
# run a 'gpg' command, you must do so from a Windows command line prompt.
# To prevent you from forgetting and accidentally running a 'gpg' command
# directly from Git BASH, you can use this script to block any attempt
# to invoke a 'gpg' command directly from Git BASH, while still allowing
# you to use Git BASH to invoke Git commands which then call gpg, as well
# as allowing you to run 'gpg' commands from Windows command line prompts.

# Place this script in your "C:\Users\<username>\bin" folder
# If that folder doesn't exist, then create it.
# Once this script is in place, if you accidentially try to
# invoke a 'gpg' command directly from a Git BASH terminal, this
# script will be invoked instead and a warning message will be displayed
# reminding you to use the Windows command prompt to directly invoke 'gpg'.
