For the font, I need the actual file name that antiX uses as its default.
No, that would be “brittle”. Don’t presume the “Day1 antiX default theme+font” has not been changed, or uninstalled.
Also the “print-gtk()” routine within env-info script mentioned by ile, it only consults ~/.gtkrc-2.0 (?are we certain that governs the default font applied within yad?)
time and date are when the screenshot was taken
instead of using a “counter”, to wind up with localized date and time plus unique filename string, you can
$(date +%F__%H-%M_%S)
and append “-thumb” for the matching thumbnail
