Small script that will open a new terminal in the working directory of the currently focused terminal. Useful with i3.

terminal-here.sh

#! /bin/bash

ID=$(xprop -root | gawk '/_NET_ACTIVE_WINDOW\(WINDOW\)/{print $NF}')
PID=$(xprop -id $ID | gawk '/_NET_WM_PID\(CARDINAL\)/{print $NF}')
SH=$(basename $SHELL)
ZPID=$(pstree -lpA $PID | sed -n "/$SH/ s/.*$SH(\([0-9]\+\)).*/\1/p")

if [[ -n $ZPID ]]
then
  CWD=$(readlink /proc/$ZPID/cwd)
fi

if ! which $TERMINAL
then
  TERMINAL=terminology
fi

if ! which $TERMINAL
then
  TERMINAL=xterm
fi

if [[ -n $CWD ]]
then
  cd $CWD && $TERMINAL
else
  $TERMINAL
fi

I use this for my i3 terminal launch. Its useful for example if you are editing a script in vim and you want to open another terminal to run the script. This script will launch the terminal from the working directory of the vim terminal.
