I am in need of a GUI bash script launcher with the ability to launch multiple scripts in parallel on wsl. I found this Python GUI script on the PySimpleGUI GitHub page. I chose it because it shows all the bash scripts in a directory and apparently; seems to allow the selection of multiple scripts using ctlr+alt+leftmouseclick. It also appears that I may be able to run them simultaneously if I desire. This is exactly what I need. I am assuming this functionality exists but I am unable to test it because it doesn’t seem to be working. I have added the appropriate directory to the code and the GUI shows the list of files in the left pane. When I select either a single or multiple files from the populated list and click "RUN"; the Pane to the right shows "Launching Program". However the script doesn’t actually run. I replaced "Popen" with "check_call to see if it would matter but nothing changed. I don’t know much about python so any help correcting this problem is appreciated.

import PySimpleGUI as sg import glob import ntpath import subprocess  LOCATION_OF_YOUR_SCRIPTS = '/home/userx/'  # Execute the command.  Will not see the output from the command until it completes.   def execute_command_blocking(command, *args):     expanded_args = []     for a in args:         expanded_args.append(a)         # expanded_args += a     try:         sp = subprocess.check_call([command, expanded_args], shell=True,                               stdout=subprocess.PIPE, stderr=subprocess.PIPE)         out, err = sp.communicate()         if out:             print(out.decode("utf-8"))         if err:             print(err.decode("utf-8"))     except:         out = ''     return out  # Executes command and immediately returns.  Will not see anything the script outputs   def execute_command_nonblocking(command, *args):     expanded_args = []     for a in args:         expanded_args += a     try:         sp = subprocess.check_call([command, expanded_args], shell=True,                               stdout=subprocess.PIPE, stderr=subprocess.PIPE)     except:         pass   def Launcher2():     sg.theme('GreenTan')      filelist = glob.glob(LOCATION_OF_YOUR_SCRIPTS+'*.sh')     namesonly = []     for file in filelist:         namesonly.append(ntpath.basename(file))      layout = [         [sg.Listbox(values=namesonly, size=(30, 19),                     select_mode=sg.SELECT_MODE_EXTENDED, key='demolist'),          sg.Output(size=(88, 20), font='Courier 10')],         [sg.CBox('Wait for program to complete', default=False, key='wait')],         [sg.Button('Run'), sg.Button('Shortcut 1'), sg.Button('Fav Program'), sg.Button('EXIT')],     ]      window = sg.Window('Script launcher', layout)      # ---===--- Loop taking in user input  --- #     while True:         event, values = window.read()         if event in ('EXIT', None):             break           # exit button clicked         if event in ('Shortcut 1', 'Fav Program'):             print('Quickly launch your favorite programs using these shortcuts')             print('''                 Or  copy files to your github folder.                 Or anything else you type on the command line''')             # copyfile(source, dest)         elif event == 'Run':             for index, file in enumerate(values['demolist']):                 print('Launching %s' % file)                 window.refresh()          # make the print appear immediately                 if values['wait']:                     execute_command_blocking(LOCATION_OF_YOUR_SCRIPTS + file)                 else:                     execute_command_nonblocking(                         LOCATION_OF_YOUR_SCRIPTS + file)      window.close()   if __name__ == '__main__':     Launcher2() 

And Here is an example of the bash script I am trying to launch.
