How can I know if a system command doesn't exist? All the ways I have
tried behave like if the system command was existing but returning one.
I don't want to sound provocative, but open in Perl returns an error
in a command doesn't exist, so I'm sure we could have an exception in
the same case for popen in Python?
Thx and Regards,
