How to repeat a dash (hyphen) in shell

Question

How can I repeat the character - n times in shell? I have read and tried this, but this does not work for -. It throws error invalid option

Answer 1

Use a for loop and number range:

for i in {1..10}; 
    do echo "-"; 
done

Or on a single line:

for i in {1..10}; 
    do echo -n "-"; 
done

which outputs ----------.

EDIT: This was before your printf edit.
