Universal SCM (Source Control Management) commands. If you always forget which SCM you are using (SVN, GIT, etc) this script is supposed to help you to abstract their common commands like: commit, update, diff. Include it in your bashrc or bash_profile

scmhelper.sh

#!/bin/bash

# Run this file to register these functions in your shell.
# You can include it in your .bashrc or .bash_profile like this:
# . ./scmhelper.sh

# Helper function that figures out which SCM
# you are using.
function getScmType()
{
  currentDir=$(pwd)
  finished=false
  scmName='unknown'

  while(! $finished); do
    if [ -d '.git' ]; then
      scmName='git'
      finished=true
    else if [ -d '.svn' ]; then
      scmName='svn'
      finished=true
    else if [ '/' = "$(pwd)" ]; then
      finished=true
