Here is a simple utility created using Python for translating text from various languages into English. It uses the Google AJAX API to do this.

Usage

prashanth@prashanth-desktop:~$ translate bonjour
hello
prashanth@prashanth-desktop:~$ translate guten morgen
Good morning

Code

#!/usr/bin/env python
'''
Translates text into english using Google Translate.
Usage: python translate.py 
        (or)
       echo  | python translate.py

For convenience, make a symlink to this file from /usr/bin/translate.
