For Loop in Linux Terminal

Question

I am using this for loop in the linux terminal:

for i in {1..21}; do

Here the script makes the loop go from 1 to 21.

How would I write the for loop, so that it goes through specific numbers; let's say:

9, 24, 29, 32, 38.

I am using Terminal on Linux.

Answer 1

For a fixed list of numbers, just put them after in separates by spaces:

for i in 9 24 29 32 38 
do 
  echo $i
done

Answer 2

third argument is incremental sequence by default it take 1

for i in {0..21..9};
do
 echo "$i"
done

but there is no pattern as you need
