wrapper script for cd (change directory) to simplify the cd ../../../.. statement

mycd.sh

#!/bin/bash

# wrapper for the cd command
# it expands sequence .... to ../../../../ (each dot becomes a ../ )
# example: ' cd .... ' -> ' cd ../../../../ '
# if the command does not match ' cd ..[.]+ ' , it is passed directly to the cd command

# alias cd=". /path/to/mycd.sh"
