# # gnome-screenshot is Mint default; has fewer options than scrot (below):
# # - <https://gitlab.gnome.org/GNOME/gnome-screenshot>
gnome-screenshot -f "$FILENAME"     # fullscreen
gnome-screenshot -w -f "$FILENAME"  # focused window

# # scrot needs to be installed: `sudo apt install scrot`
# # - <https://manpages.debian.org/testing/scrot/scrot.1.en.html>
# # - <https://github.com/resurrecting-open-source-projects/scrot>
scrot "$FILENAME"       # fullscreen
scrot -u -b "$FILENAME" # focused window (with border)
scrot -q 75 "$FILENAME" # set JPG compression level


# One-liners:
gnome-screenshot -f "$HOME/Pictures/Screenshots/$(date +"%Y-%m-%d %H-%M-%S %3N").jpg"
scrot "$HOME/Pictures/Screenshots/$(date +"%Y-%m-%d %H-%M-%S %3N").jpg"
