The other day I was thinking about all those sentences I had to write while in grade school (primary). It would have been great to know something about the repeat command. In all seriousness, you can use it as a separator (maybe script output). Here are some examples of its use.
# repeat 5 echo "*********"*********
*********
*********
*********
*********
# repeat 5 echo "##########"
##########
##########
##########
##########
##########
# repeat 5 echo " "
# repeat 500 echo "I will not chew gum or backtalk."
I will not chew gum or backtalk.
I will not chew gum or backtalk.
I will not chew gum or backtalk.
I will not chew gum or backtalk.
I will not chew gum or backtalk.
...
You get the idea
