check parameters

hi all,

i write a script in ksh but i have a problem
I want to check the number of parameters


while [[ $a -gt 0 && $CLIENT != fine ]]
do
echo "Inserisci la macchina che vuoi restorare o scrivi fine per terminare lo script, puoi restorare" $a "client: "
read CLIENT
echo $CLIENT

the variable $CLIENT must be FINE or name of one client and cannot acept another variable .
how can i do?

$# gives the number of parms on the command line.

Ok. How can you know you have a client name? you have to test for that.
Note: I use "| grep -q "$CLIENT"" , your grep may not support that,
so use "| grep $CLIENT > /dev/null"
Code:
all_clients="Paulo|Maria|John"
while true
do
   read CLIENT
   [  $CLIENT = "fine" ] && exit           # this completely exits from the whole script
   echo "$all_clients" | grep -q "$CLIENT"
   if [  $? -eq 0 ] ; then  # we found a good client 
      # do something with $CLIENT here
   else
       echo "$CLIENT not a valid answer"
   fi
done

Satrt with this code.
