How to redirect a file to a directory?
Again, the redirection operator has no notion of the source of its input – no idea that originally came from a file, let alone what that file is called.

Is there a way to automatically generate directories in Python?
This gives an IOError, since /foo/bar does not exist. What is the most pythonic way to generate those directories automatically? Is it necessary for me explicitly call os.path.exists and os.mkdir on every single one (i.e., /foo, then /foo/bar)? The os.makedirs function does this. Try the following:
How to redirect input to another file in Linux?
Each file in Linux has a corresponding File Descriptor associated with it. The keyboard is the standard input device while your screen is the standard output device. “>” is the output redirection operator. “>>” appends output to an existing file. “<” is the input redirection operator. “>&”re-directs output of one file to another.
