# Script Description:
|
|
# This script connects an existing local directory to a remote Git repository.
|
|
# It requires the SSH URL of the Git repository as an input argument.
|
|
#
|
|
# Process:
|
|
# 1. Initializes a new local Git repository.
|
|
# 2. Adds the provided URL as the remote 'origin'.
|
|
# 3. Fetches the remote repository data.
|
|
# 4. Checks for differences between the local files and 'origin/master'.
|
|
# 5. If there are no differences, it sets up tracking for the master branch
|
|
# and performs a hard reset to synchronize exactly with the remote.
|
|
#
|
|
# Usage:
|
|
# ./connect_git.sh <repository-ssh-url>
|
|
#
|
|
# Example:
|
|
# ./connect_git.sh git@github.com:username/repository.git
|
|
# ==============================================================================
|
|
|
|
# Check if the repository URL argument is provided
|
