Well, that was totally obvious ;) However a few more pointy brackets in combination with [] and $ in the mix would have been nice, too! Feels almost like the STL API! ;)

That's a trick question! Because an echo repeats everything you say it would be sufficient to escape with half the number of backslashes as needed. But since we need 7 of them which cannot be divided by 2 without fractional part the use of echo here is impossible and might even format your harddrive (twice!).

Every Unix crack knows that ;)
