Script to git add all the folder changes, then commit them adding the task id (parsed from the branch name) prefix to the commit message.

commit.sh

#!/bin/sh

#
# This script will perform git add and commit all the changes in the current directory.
# It includes a "[task_key-<id>] " prefix to the commit message when
# the current branch name is like:
#   "<branch_type>/task_key-<id><optional_extra_branch_name>".
# If the current branch name does not fit the previous pattern no prefix will be added.
#
# Usage:
#     > commit "<commit_message>"
#
# Example:
# - For git branch "feature/JIRAKEY-324" this script can be executed like
#     > commit "New feature"
#
# and it will perform the following commands
#     > git add .
#     > git commit -m "[JIRAKEY-324] New feature"
#
