I’m stuck on Stage #GY5
My program passes all the completion tests, but fails at the append std out/err test by echoing the command, the behaviour is not consistent:

cat and ls are executed by subprocess.run() function:
case default:
if identifier := shutil.which(identifier if identifier else ''):
subprocess.run(command_foo, shell = True)
else:
print(f'{command}: command not found')
where command_foo variable is a string copy of inputted command
