Merging branches is another common task that can be automated to avoid conflicts and errors:

#!/bin/bash

# Check if branch name is provided
if [ -z "$1" ]; then
  echo "Please provide a branch name to merge into the current branch."
  exit 1
fi

# Fetch the latest changes
git fetch origin

# Checkout the current branch and merge
git checkout "$1"
git pull origin "$1"

# Merge the specified branch into the current branch
git checkout -
git merge "$1"

# Push the changes to the remote repository
git push

echo "Merged branch '$1' into the current branch and pushed changes."
