Thx for shearing!

string $selection[] = `ls -sl`;

for ($myNode in $selection) {

    $smoothState = `getAttr ($myNode + ".displaySmoothMesh")`;
    if($smoothState != 2) {
        $smoothState = 2; 
    }
    
    $displaySubdCompState = `getAttr ($myNode + ".displaySubdComps")`;
    if($displaySubdCompState != 1){
        $displaySubdCompState = 1;
    }
    
 setAttr ( $myNode + ".displaySmoothMesh") $smoothState;
 setAttr ( $myNode + ".displaySubdComps") $displaySubdCompState;
}

Edit: it doesnt work in sub-object mode.
