While command

The syntax of the while command is

while list1

do list2

done

qsh runs the two lists repeatedly while the exit status of list1 is zero. When the exit status of list1 is non-zero the command completes.

Examples

1. A while command to iterate until a condition is met.

   max=100
   index=0
   while [[ $index -lt $max ]] ; do
     echo Index is $index
     let index+=1
   done
