Change directory upwards to the first directory containing a .git directory. Helpful in quickly getting to the root of a git project.

.bashrc

cdg () {
  CD="`~/bin/cdg.sh`"

  cd $CD
}

cdg.sh

#!/bin/bash

PATH="./"
LASTPATH="$PATH"

while [ 1 -eq 1 ]
do
  if [ `/usr/bin/find "$PATH" -maxdepth 1 -type d -name ".git" | /usr/bin/wc -l` = "1" ]
  then
    echo "$PATH"
    exit 0
  else
    LASTPATH="$PATH"
    PATH="$PATH../"

    # Exit if this is the highest directory available -- no .git found
    if [ `/bin/readlink -f "$PATH"` = `/bin/readlink -f "$LASTPATH"` ]
    then
      echo "./"
      exit 1
    fi
  fi
done
