Unix - ksh test if multiple variables are 0
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."

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."

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

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."
