How to make an os.system call, without the pop up of the dos-box???

Peter,

Use the os.spawnv(mode, path, args) function.

The spawnv mode parameter sets the execution mode of the called process,
here are the two most common modes:

os.P_WAIT - waits for the called process to complete before resuming
execution of your script.

os.P_DETACH - calls the new process and continues to run your script.

The path parameter is the path to the called process.

The args paramter contains a list or tuple containing the command line
arguments for the called process.


Example:

os.spawnv(os.P_WAIT, 'rmdir', (' ', '/S', '/Q', r'C:\arwa\dev\'))

There is a bug in the 1.5.2 spawnv call!! You need to add a space to
the first argument, or the command line args will not be processed
properly.  I get around this by passing a single space as the first
argument.

I use this workaround method in the above example.
