How Can I Get an Icon or thumbnail for a Specific file

Question

I am searching for a way to get the icon associated with a certain file type on Linux.

Either using a shell script or python.

I prefer a native python method whi

Answer 1

I found a solution, and I wrote a function to do the job

#!/usr/bin/env python
import gio, gtk, os

def get_icon_filename(filename,size):
    #final_filename = "default_icon.png"
    final_filename = ""
    if os.path.isfile(filename):
        # Get the icon name
        file = gio.File(filename)
        file_info = file.query_info('standard::icon')
        file_icon = file_info.get_icon().get_names()[0]
        # Get the icon file path
        icon_theme = gtk.icon_theme_get_default()
        icon_filename = icon_theme.lookup_icon(file_icon, size, 0)
        if icon_filename != None:
            final_filename = icon_filename.get_filename()
    return final_filename
            
        
print (get_icon_filename("/home/el7r/Music/test.mp3",64))

thanks all
