If you want to remember last working directory you can add this into .bashrc

# cdp() will create or rewrite file ~/.cwd with working path
cdp()
{
  cd "$1"
  echo `pwd` > ~/.cwd
}

# exporting cdp() to shell as a command
export -f cdp

# changing working directory if file exists
if [ -d `cat ~/.cwd` ]; then
  cd `cat ~/.cwd`
fi
