# Script Description:
|
|
# This script connects an existing local directory to a remote Git repository.
|
|
#
|
|
# Process:
|
|
# 1. Initializes a new local Git repository.
|
|
# 2. Adds the remote 'origin'.
|
|
# 3. Fetches the remote repository data.
|
|
# 4. Stages local files to check differences.
|
|
# 5. Identifies real changes bypassing the Git --name-only whitespace bug.
|
|
# 6. Prompts to override local files if diffs are found.
|
|
