Not the biggest hurdle, but I felt like THE BOSS on finishing the task.
I have to create Branch in a repository for respective folders in S3 bucket and have to commit that folder into it's respective branch. There are around 29 folders in the bucket, the task would have taken my entire day. Rather I completed the task in less than half an hour. Shell Script is the coolest tool, which saved my entire day, indeed I felt like THE BOSS.
