Here’s the traditional way of displaying a list of dashes across the screen.

echo "===================="

Here’s the short cut.

printf -- '=%.s' {1..20}; echo


  • first I’m using printf instead of echo. printf is a little bit better when it comes to formatting.
  • The – option tells printf to ignore the rest of the remaining arguments so it renders properly.
  • The character before the % percentage is the one being repeated. In this case, we are repeating “=.”
  • 1-20 is the number of times the character before the % percentage is repeated.

That’s it.
