Some time we need to share files to other systems in our computer center quickly with out any tools in hand. If you have a python installation in your system, file sharing is very simple by implementing a little http server, using a single line command.
Suppose If you want to share the folder /home/shibu/ and my IP address is 192.168.0.4
open a terminal then type following
$ cd /home/shibu
$ python -m SimpleHTTPServer
Now your http server will start in port 8000
