Applying Aim Constraint to multiple groups at once

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

for ($tmp in $sel) {

aimConstraint -offset 0 0 0 -weight 1 -aimVector 0 1 0 -upVector 0 1 0 -worldUpType "vector" -worldUpVector 0 1 0 Locator $tmp;

};

items in italics can be edited to suit requirement. "Locator" = name of target to orient towards.
