#!/bin/bash

### mxfb-menu-generator: a tiny script to Create a (non dynamic) fluxbox menu using information on .desktop files, released by PPC, 7/10/2020, under GPLv3
### Modified by MX Linux Devs for use in MX-Fluxbox August 2021

### How to use this script:
### 1. Copy the script below and paste it into your text editor, saving it in your Home as MXFB_menu_generator.sh
### 2. Navigate to that file, right click it > Proprieties > "Permissions" tab > Check the last field, to allow this script to run as a program
### 3. Add the following entry to your menu to access "All Categories" anywhere you want 
#######################################################################################   
#[submenu] (All Apps)
#       [include] (~/.fluxbox/submenus/full_menu) 
#       [separator]
#       [include] (~/.fluxbox/full_menu)
#   [end]
#######################################################################################
### 4.- Now click Menu > All apps > Update menu. Wait for some seconds while the menu is generated
