Script for keeping your windows and applications handy

thewindow.sh

usage()

cat << EOF
usage: thewindow [OPTIONS] SEARCH_STRING COMMAND

This script will search the X window manager for any open window containing SEARCH_STRING and, if found, will move to the containing desktop, raise that window, and give it focus.

If a matching window on the current desktop is found, that will be focused first instead of any matching windows on other desktops.

If the matching window already has focus, and another window on the same desktop matches SEARCH_STRING, that other window will be focused. This way you can cycle between multiple instances of the same application open on one desktop (currently, however, it will only cycle you between the first 2 windows listed by wmctrl).

If no matching window is found, COMMAND is run.

Good for keeping handy your browser, terminal, code editor, chat application, file manager, etc.

OPTIONS:

   -h      Show this message
   -c      Only activate a matching window on current desktop, otherwise run COMMAND
   -v      Verbose mode (logs to /tmp/thewindow.log for easy use via shortcut)
