Tux Paint responds to the following signals (which can be sent to the
program's process via `kill` or `killall`, for example).
SIGTERM (also, [Control] + [C] from a terminal running `tuxpaint`)
Tux Paint responds as if the "Quit" button were pressed, or the
desktop environment was told to close Tux Paint (e.g., by clicking
a window close button, or pressing [Alt] + [F4] on most systems).
From the main interface, Tux Paint will prompt whether or not you
wish to quit, and (unless overridden by the auto-save option, e.g.
"--autosave") if you'd like to save the current drawing (if
unsaved), and if so, and it's a modified version of an existing
drawing (unless overridden by the options to save over old images,
or always save new images; e.g. "--saveover" and "--saveovernew",
respectively), whether or not to overwrite the existing drawing,
or save to a new file.
Example: killall tuxpaint
💡 Note: From other parts of the interface, the signal is currently
interpreted as a request to go back (e.g., from the "New" dialog
back to the main interface), as if a "Back" button in Tux Paint
were clicked, or the [Esc] was key pressed.
SIGUSR1 & SIGUSR2
Tux Paint responds by setting its auto-save option (as if it had
been launched with "--autosave"), as well as either the option to
always save new images (as if launched with "--saveovernew") in
the case of receiving a SIGUSR1 signal, or to always save over the
existing image (as if launched with "--saveover") in the case of
receiving SIGUSR2. Then Tux Paint sends itself a SIGTERM signal,
in an attempt to quit. (See above.)
So, from the main interface, Tux Paint should quit almost
immediately, with no questions asked.
Example: killall -s SIGUSR1 tuxpaint
💡 Note: From other parts of the interface, unfortunately, Tux
Paint will go back one level in the interface. Therefore, at this
time, it may be necessary to send this signal to Tux Paint a few
times, for it to quit completely.
