[mckarl]

hi all, well... i need a random number in my shell script.<br>- and the best way i have found is:<br><br>------------------------------------------------------------<br><br>echo &quot;Three numbers will now be chosen at random.&quot;<br><br>ran1=$RANDOM<br>ran2=$RANDOM<br>ran3=$RANDOM<br><br>size1=${#ran1}00<br>size2=${#ran2}00<br>size3=${#ran3}00<br><br>random1=`expr $ran1 / $size1`<br>random2=`expr $ran2 / $size2`<br>random3=`expr $ran3 / $size3`<br><br>echo &quot;1. $random1&quot;<br>echo &quot;2. $random2&quot;<br>echo &quot;3. $random3&quot;<br><br>------------------------------------------------------------<br><br>Please tell me there is an easier/better way to do this!!&nbsp;&nbsp;<br><br>Thankyou in advance, Karl.<br> <p> Karl<br><a href=mailto:mc_karl@yahoo.com>mc_karl@yahoo.com</a><br><a href= > </a><br> ~ ~ ~ ~<br>

It´s a good way, but try multiplying or dividing a pair of random numbers... it´s better. Or you can use SECONDS var too.<br><br>I hope it works...

What i hope to do, is specify a range of numbers&nbsp;&nbsp;( ie 1-10)<br><br>-- so i can generate a number between those numbers.<br><br>there is the RANDOM<i>=10</i> thingy, but i dont really know how that works... <br><br>-- Please can someone tell me the answer??<br><br>---- Thanks in advance, karl! <p> Karl<br><a href=mailto:mc_karl@yahoo.com>mc_karl@yahoo.com</a><br><a href= > </a><br> ~ ~ ~ ~<br>

I guess is easier to divide thr RANDOM number by 3277 and add 1. That willgive you numbers between 1 and 10<br><br>Ihope it works..
