Coding The Wallpaper Changer Function

CD
# I am using nvim, you can perform this operation with any text editor (nano, pico, gedit etc.).
nvim .zshrc

Find the file named .zshrc on your system and add the following code block to the bottom line:

# change desktop wallpaper
changewall(){
     gsettings set org.gnome.desktop.background picture-uri "$(find ~/Pictures -type f | ff)"
}

Explanation

• gsettings: It is the command that makes system settings for GNOME
• set: specifies the value to be assigned to the operations to be performed
• org.gnome.desktop.background: indicates that changes will be made to the background within the system.
• picture-uri: indicates the point in the system where the path to the file to be changed is located.
• find: Used to find the full file path of the file. -type f indicates that the file is being searched.
• fzf: the tool we will use to search for files
