Hi there again,
I'm still a newby in Python, so I'm taking the Google Python Class.
They talk about
ls -l and
rm -rf (with the last command the class started laughing)
But I don't understand it.
I googled it and a hint came to me, that is is a regular expression.
But I can't seem to find the true meaning of these RE's.
Can someone please explain what they do and maybe give me a website where I can find more of these expressions?
