Launch new xfce4-terminal starting in the working directory of the current xfce4-terminal or pwdx

xfce4-terminal-pwd.sh

#!/bin/bash

# Little script hack that launches a new xfce4-terminal with the
# current working directory as its default. Mimics pwdx with
# xfce4-terminal (all of whose windows share a single process for
# perfomance) by extracting the cwd from the window title.  If the
# ACTIVE_WINDOW isn't a xfce4-terminal, use pwdx of the current
# window's PID.
