I'm developing a Tkinter app for a Windows customer, and the app bundles
several command-line tools (ported from Unix). I call out to these
console tools from the Tkinter app via os.system(). However, in the
frozen version of my app, when I call out to these tools, I get multiple
console windows popping up. This is jarring to say the least. Is there
any way to run the commands under the hood without the console/DOS
windows popping up?
Just a wild guess, but try explicitly redirecting the commands'
stdin/stdout/stderr. You might also consider using subprocess.call()
instead of os.system().
I've gotten the CLI commands to execute silently by setting the window
flags for subprocess as discussed here:

These flags are apparently undocumented, but this solution works
perfectly. Perhaps the flags should be better documented.
