How to use if command to compare in an array?
Hi all,


Currently i am facing issue using if command to compare to array value.

can someone help me?

Code:
if [ "${ZZZLAST_DATAIN_TIME[$i]}" -gt "${ZDATE_1[$i]}" ]
then
do
echo "red"
else 
echo "green"
fi
done

i have checked array is giving values fine but there seems some issue with if command.

What errors are you encoutering? Are those array values integers or strings? -gt is for comparing integers only.

I got the answer.

below is the code that worked for me.

Code:
for((i=0;i<15;i++))
do
if [ "${ZZZLAST_DATAIN_TIME[$i]}" -gt "${ZDATE_1[$i]}" ]
then
echo "YES"
else 
echo "no"
fi
done
