I use the START command sometimes. For example, in the
*execute-external-file* command, I have this bit:
if processor == 'cmd.exe':
cmd = ['start', processor, '/k', fullpath]
subprocess.Popen(cmd, shell=True)
else:
cmd = ['start', 'cmd.exe', '/k', processor, fullpath]
subprocess.Popen(cmd, shell=True)
But START can be tricky. For example, if the first parameter on the
command line is in double quotes, it is used as the title of the window.
If you don't realize that and the program you are STARTing needs to have
its path quoted, START won't work because you program path will become the
title and the next arg, if any, will become the program to execute, which
is not what you want. You have to use a pair of double quotes to avoid the
problem: START "" "quote path to program to run". START has other quirks
too.
I find it's easy to get confused about output when two programs run in the
same console - who is printing to the console just now? There's also the
matter of how to terminate a program if it gets stuck or you are done with
it.
One approximate equivalent on Linux is to end the command line with an
ampersand. This launches the program and its output goes to the terminal
as usual. If you hit CTRL-z, it executes in the background and you can use
the terminal for other things too. the *jobs* command will show background
programs.
