Check multiple variable in if statement in bash script using && operator [duplicate]

Question

if statement is not working

if [ "$diff" -eq 1 ] && [ "$diff1" -eq 1 ] && [ "$diff3" -eq 1 ];

then

$ch=1

fi

please anyone help me with this.

error is [: : integer expression expected

In bash this works: if [ "$diff" == 1 ] && [ "$diff1" == 1 ] && [ "$diff3" == 1 ]; or if [ $diff -eq 1 ] && [ $diff1 -eq 1 ] && [ $diff3 -eq 1 ]; — mnille

You can try like this,

if [[ ("$diff" == 1 && "$diff1" == 1  &&  "$diff3" == 1) ]]; then
    $ch=1
fi
