Run A Command Repeatedly Several Times

From the terminal in a Bash or Zsh shell session, I can loop on a command to have it run a specific number of times.

If I want to run a test command (e.g. bin/test some_file.spec:123) 12 times in a row, I could use a for loop like so:

for i in {1..12}; do bin/test some_file.spec:123; done

And the shell will run the command one time after another until it has been run 12 times. That range {1..12} can be adjusted to whatever I want. For instance, to have it loop 3 times, I'd make it into {1..3}.
