Your guesses about my own morality were quite amusing, bordering on silly. I loved when you wrote, "YOU are the one helping to enslave them...." Truly inspired. I congratulate you on a fine, industrial-strength troll.
Ah. You believe the myth of the happy prostitute.
Picking up runaways off the street, forcing them into prostitution, and getting them indebted and hooked on drugs so they can't leave, is not a victimless crime. Making prostitution legal will not prevent this; there are always girls down on their luck, and always scum ready to prey on them.
1. find piped into xargs (or "find -print0" piped into "xargs -0" for safety) to process a directory tree in a single command
2. Printing commands on stdout and piping them into bash. For example, if you want to rename a bunch of files, and you put the old names into file "oldnames" and the new names into "newnames", one per line, you can do the mass renaming with:
$ paste oldnames newnames | sed 's/^/mv
generates a sequence of "mv" commands and executes them.
First time I saw each of these, it was so eye-opening.
Always draw your curves, then plot your reading.
