when do we use set -k option in bash? that got it to work, but its still a mess of problems. price listed is our trade price for a pack of 4 units. we are happy to exchange or issue a credit note for any item up to 28 days after purchase date. i' m not sure why but i think its a linking issue. cleaning supplies, food wrappers, plants, and more can harm pets. i am married to a wonderful man, rod. we may or may not agree with everything one person believes.
