Unix - ksh test if multiple variables are 0












1















So basically I want to test if 3 variables are 0. If one of them is not it should report it. This is what I got:



        if [[ $result -ne 0 && $resultmax -ne 0 && $resultmin -ne 0 ]]
then
echo "There is something terribly wrong."
fi


It does not work. Any idea where I messed up?

          If you want to test that one of these variables is not 0, then you need || operator. Not &&.



          $ if [[ 1 -ne 0 && 0 -ne 0 && 0 -ne 0 ]] ; then echo "There is something terribly wrong.";  fi

          $ if [[ 1 -ne 0 || 0 -ne 0 || 0 -ne 0 ]] ; then echo "There is something terribly wrong."; fi
          There is something terribly wrong.

            Now you are testing if all variables are not 0 to report error. Try:



            if [[ $result -ne 0 || $resultmax -ne 0 || $resultmin -ne 0 ]]
            then
            echo "There is something terribly wrong."
            fi

              To test if any of the variables is not 0 use the or operator || (as already suggested):



              if [[ $result -ne 0 || $resultmax -ne 0 || $resultmin -ne 0 ]]
              then
              echo "There is something terribly wrong."
              fi


              Though, if you're doing numerical computation and are using ksh (or bash, or zsh) you might prefer to use this syntax for clarity:



              if (( result != 0 || resultmax != 0 || resultmin != 0 ))
              then
              printf "%sn" "There is something terribly wrong."
              fi
