Update current branch from branch "develop"

gitMergeLatestIntoCurrentBranch.sh

#!/bin/bash

MAIN_BRANCH=${1:-develop}

echo
echo "Fetching..."
git fe

echo
echo "Switching to $MAIN_BRANCH..."
git co $MAIN_BRANCH

echo
echo "Pulling $MAIN_BRANCH..."
git pull

echo
echo "Switching back..."
git co -

echo
echo "Merging $MAIN_BRANCH..."
git merge $MAIN_BRANCH

I use in the script the aliases. These aliases are defined in another gist.
