I'm working on a pdf2ps frontend script that will use the *nix utility
"file" to determine a file's type without blindly trying to work on it. I
assume the best way to do this is to spawn "file", capture its stdout to a
string variable, and then use regular expressions to search within the
captured stdout for the file type desired (in this case PDF). However,
I've tried these:
capturedstdout = os.system(["file"]+foo)
capturedstdout = swapvp('P_NOWAIT', 'file', ['file']+foo)
but these don't work because the return value of file is assigned to the
variable "capturedstdout", not the stdout. How do I spawn a program and
have its stdout assigned to a string variable?
