Right click to run script in Nautilus

Here is how I setup this script: Nautilus can set desktop wallpaper. How can it set login and lock screen wallpaper?.

After using Nautilus to navigate and view an appropriate .png or .jpg file to use as login screen and lock screen wallpaper, Nautilus can set this for you using a script.

To create the script use:

cd ~/.local/share/nautilus/scripts/
gedit set-login-wallpaper

Paste in these lines:

#!/bin/bash

## Set login wallpaper

# strip new line char passed by Nautilus
FILENAME=$(echo $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS | sed -e 's/\r//g')

# Multiple files can't be selected.
LINE_COUNT=$(wc -l <<< "$NAUTILUS_SCRIPT_SELECTED_FILE_PATHS")
LINE_COUNT=$((LINE_COUNT-1))

if [[ $LINE_COUNT > 1 ]] ; then
    zenity --error --text "Ony one file can be selected at a time! "
    exit 1
fi

# Object type must be "file..." (ie no directories, etc.)
if [ -d "${FILENAME}" ] ; then
    zenity --error --text "$FILENAME is a directory!";
    exit 1
else
    if [ -f "${FILENAME}" ]; then
        : # Bash noop
    else
        zenity --error --text "${FILENAME} is not a file!";
        exit 2
    fi
fi

# Build working file in /tmp
echo "[com.canonical.unity-greeter]" > /tmp/set-login-wallpaper.tmp
echo "draw-user-backgrounds=false" >> /tmp/set-login-wallpaper.tmp
echo "background='$FILENAME'" >> /tmp/set-login-wallpaper.tmp

# Must run as sudo
if [ "$EUID" -ne 0 ] ; then

    # Get sudo password
    PASSWORD=$(zenity --password --title="Set Login Wallpaper" --timeout=20)

    # copy working file to real file using sudo
    echo $PASSWORD | sudo -S cp /tmp/set-login-wallpaper.tmp \
/usr/share/glib-2.0/schemas/10_unity_greeter_background.gschema.override

    # compile using sudo
    echo $PASSWORD | sudo -S glib-compile-schemas /usr/share/glib-2.0/schemas

else
    # Already sudo so simply copy and compile
    # copy working file to real file
    cp /tmp/set-login-wallpaper.tmp \
/usr/share/glib-2.0/schemas/10_unity_greeter_background.gschema.override

    # compile
    glib-compile-schemas /usr/share/glib-2.0/schemas
fi

exit 0

Save the file and exit the gedit editor.

Now mark the script as executable using:

chmod +x set-login-wallpaper

Open Nautilus and navigate to your directory with wallpaper images. Find an appropriate image and right-click on it. This drop-down menu appears:

Nautilus Right Click Drop Down

Click on the third option Scripts. Another drop down menu appears with all your scripts:

Nautilus set-login-wallpaper Drop Down

Select set-login-wallpaper.

When the script runs you will have to enter your sudo password.

Reboot and enjoy your new login and lock screen wallpaper.
