Die shell script, DIE !
In this post, I'll show how easy it ease to convert fragile shell scripts to Python scripts, using sh.py. I'll use as an example a simple script to check your HTML code from the command-line, using the W3C validator.

What do you think it produces ?
Not necessarily "ABCDE". Right, but you would expect the result to be consistent, isn't it ?
