I am trying to scan (our) website with a script, that's basically a more detail wget command, that takes $1 as the url.

Somehow the redirection to the outfile (with $RANDOMoutfile) does not work. I had it in the script previously, but then I get a lot of different outnames.  I also tried 4x : and 3x :, that seemed not to make a difference.

I used this with another script, and it seemed to work fine (except that it ran only on one core )

$RANDOM is a built-in variable in bash given a random value each time you read it.

eg.

$ echo $RANDOM-andreas
455-andreas
$ echo $RANDOM-andreas
23322-andreas
$ echo $RANDOM-andreas
4469-andreas
