#!/bin/bash
# by varacanero@zeromail.org
# under gpl licence v3
# Usage:
# * check if wait_for_prompt() is working correctly by running shelr-screencast.sh ~/coding/xdotool/script
# * in order to get this working, you need sth like this in your .bashrc:
# PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD/$HOME/~}\007"'
# * open another terminal, not bigger than 132x43
# * gain temp. sudo priviledges with "sudo /bin/true"
# * start "shelr record"
# * start this script in another terminal i.e. "./shelr-screencast.sh /home/varac/coding/xdotool/script"
# * move mouse focus to shelr window !
# Limitations
# to query if a window is processing some cmd of is waiting with a shell prompt,
# you can't su to another users, cause xprop would not recognize running cmds.
# you need to run this as the xsession user
# for tty backend ~350
