Git file testing and puhing if ok

#!/bin/bash

### This script is intended to be used from inside a git repository (Say any folder where git status would not fail)
### It is intended to be stored on a path folder to be used directly as follows:
### $ gitc ['comment']
###
### If comment is missing it will still prompt asking for a comment, if no input it would use the default_comment value '-.-'

default_comment='-.-'
