If you have a recent version of Bash:for i in {1..3}; do    for j in {10..50..10}; do        echo $i $j    donedoneIf you have an older version:for i in {1..3}; do    for j in {1..5}; do        echo $i ${j}0    donedoneOr, using seq:for i in $(seq 1 3); do    for j in $(seq 10 10 50); do        echo $i $j    donedone
