I always avoided Bash scripting whenever I needed anything programmer-ish, like functions, looping or control structures. Back then, I could pick my favorite tool for whatever the job. Problem: Now I am working in a situation where the preferr...

For example: >>>$ python Python 2.6.4 (r264:75706, Dec 7 2009, 18:45:15) [GCC 4.4.1] on linux2 Type...
