When leaving X and returning to the console, most window managers will forcefully destroy all windows still open, giving you no chance to gracefully close some applications.

Bouncer sends _ NET_CLOSE_WINDOW messages to every window matching a pattern and blocks until all those windows are closed or a specified timeout expires.

Simply running

make install

as root will install the binaries to /usr/bin, configuration to /etc and MAN-pages to /usr/share/man/. If you want to install to a fake root directory (e.g. for package creation) use the prefix-variable.

make install prefix=/fake/root

The subdirectories usr/bin, usr/share/man and etc must exist.

make debug

Compiles source files without optimizations and with debugging informations (-O0 -g).

Instead of just calling

$ shutdown -h

you could call

$ bouncer -t 30 -p "Firefox" && shutdown -h

This will send a _NET_CLOSE_WINDOW message to every window with the string "Firefox" in its WM_CLASS property and wait until they are closed or 30 seconds elapsed.

As root you can call

$ bouncer-global -t 30 -p "Firefox" && shutdown -h

to affect all Displays.

The file ~/.bouncerc can be used as alternative to the -p argument.

I want a systemd service to run before shutdown but I can't get it to work. So, if anyone's more into this...
