HOW TO read current XFCE wallpaper or background file name [SOLVED]

[spamhog]

Why?
- a cool wallpaper shown by e.g. random changer isn't easy identified (mine come from a ~5k image dump, the GUI desktop settings preview window takes ages to fill)
- setting location in the tree changed over time
- so past magic formulas become wrong.

BE EXTRA CAREFUL WITH XFCONF AS IT MAY CHANGE SETTINGS

As of April 2021, Mint 20.1 XFCE, you find it like so:

Code: Select all

xfconf-query -c xfce4-desktop -lv | grep "last-image"

As a .desktop button, save e.g. as current-background.desktop :

Code: Select all

[Desktop Entry]
Version=1.0
Type=Application
Name=CURRENT BG
Comment=:-D
Exec=xfce4-terminal -e 'bash -c "xfconf-query -c xfce4-desktop -lv | grep "last-image"; bash"'
Icon=
Path=
Terminal=false
StartupNotify=false

Explanation:
- it's in the xfce4-desktop channel
- grepping "last-image" shows all wallpapers for all vitual desktops.

In the future path may change, so update by going to Menu - Settings - Setting Manager, don't change anything there, nose or search around, make a note of channel and some identifying string.
