Random password generating function

mkpasswd() { head -c $(($1)) /dev/urandom | uuencode - | sed -n 's/.//;2s/\(.\{'$1'\}\).*/\1/p' ;}
This uses urandom to produce a random password. The random values are uuencoded to ensure only printable characters. This only works for a number of characters between 1 and 60.
Sample Output
$ mkpasswd 56
$ mkpasswd 9

What Others Think

Actually, you can just do "head -c $1". I originally was diving by 3 to reduce the amount of random characters needed (in case I switched to random), but then forgot that I stopped doing any math on the value.

And, actually, a little smaller is: mkpasswd() { head -c $1 /dev/urandom | uuencode - | sed -n '2s/.\(.\{'$1'\}\).*/\1/p' ;}

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
