Or would you prefer using 'date'?</div></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><br><div class="gmail_quote">On Tue, Mar 19, 2013 at 10:22 PM, Erik de Castro Lopo <span dir="ltr"><<a href="mailto:mle+la@mega-nerd.com" target="_blank">mle+la@mega-nerd.com</a>></span> wrote:<br>

</div>Arithmetic support is actually not the issue, rather its that dash/sh<br>
doesn't support $RANDOM. The solution to this is to replace $RANDOM<br>
with $(date +%N) which is obviouslsy not all that random, but which<br>
is close enough to random for this usage.<br>
<br>
Since Jaren is in the process of making the scripts POSIX shell<br>
compliant, I think swicthing to bash is a bad idea :-).<br>
<br>
I was going to do the $RANDOM to $(date +%N) conversion after Jaren's<br>
POSIX patches were all applied.<br>
<br>
Cheers,<br>
