Using While

[tdfreeman]

I am trying to figure out how to use while. I am testing a script and get an error: bad number. The following is my script. Any ideas?

#!/bin/ksh
file1=/usr/users/oracle/TEST/out_PBBV

while (( ! -a $file1 ))
do
cp temp temp1
done

while [ ! -a $file1 ]
do
cp temp temp1
done vlad

|#include<disclaimer.h> |
+---------------------------+

Thanks. That worked.
