How to create a loop in bash that is waiting for a webserver to respond?

It should print a \".\" every 10 seconds or so, and wait until the server starts to respond.

The use of backticks ` ` is outdated. Use $( ) instead:

until $(curl --output /dev/null --silent --head --fail http://myhost:myport); do
  printf '.'
  sleep 5
done
