Spawn/Exec with asterisk in argument
The spawn* and exec* functions appear to escape asterisks, I'm
guessing all shell characters too, before the spawn/exec'ed process
sees them. Is there a way around this?
Not sure if this is a bug or a "feature".
user$ touch test.txt
user$ ls -l *

user$ ls -l \*
ls: *: No such file or directory

Thanks for the reply Michael. I used ls as a simple example, but I'm
using this with scp to transfer files and need shell expansion. It
makes sense since the shell isn't spawning the process, but it's been
a while since I've worked with ipc. I had converted to os.system
before posting, but subprocess gives me more control than I originally
hoped for
Thanks again
