Hi everyone,

For the fun of it, I am trying to write a shell program similar to Linux's bash or Windows' command. I'm writing the program on Windows, and this is what I have so far:

(Toggle Plain Text)

import os

os.chdir('/') #Change the directory to Windows root

while True:
    directory = os.path.abspath(os.curdir) 
    directory += '>>'
    prompt = raw_input(directory) #Print the command line prompt as C:\>>

So far, it waits for the user's input by looping C:\>>.

My next step is to actually make the shell respond to user commands. For example, if the user inputs put "Text here" the shell will interpret the statement as print "Text here".

I think the best thing to use is a parser or string methods. The problem is that I haven't found many docs on either item, and am not sure how to implement this. Does anyone here have a tutorial or an example on how I would parse text so that python can interpret it and do what I want? (I also want to do things such as change directory with a command like dir <dir here> and so on.)

Thanks
