I have started my daily drawing journey which i still am bad at it. To create a new .kra files files every day I use this
#/usr/bin/bash
days=$(</var/home/monika/scripts/days)
echo "$days"
file_name=/var/home/monika/Pictures/Art/day$days.kra
if [ -f $file_name ]; then
echo file is present
else
if [[ $days%7 -eq 0 ]]; then
echo "Week completed"
fi
cp "/var/home/monika/scripts/duplicate.kra" $file_name
flatpak run org.kde.krita $file_name
echo $(($days + 1)) >/var/home/monika/scripts/days
fi
JUST MONIKA
