Until command

The syntax of the until command is

until list1

do list2

done

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

Examples

   index=0
   until [[ $index -eq $max ]] ; do
     echo Index is $index
     let index+=1
   done
