`puts` puts an EOL, `print` doesn't. `p` does something else! – not2qubit Jan 25 '22 at 22:12

Use print instead.
You may want to follow it up by STDOUT.flush.

For your information. `STDOUT.flush` flushes any buffered data within ios to the underlying operating system. ```$STDOUT.print "no newline" $STDOUT.flush``` produce ```no newline``` – XY L Dec 21 '14 at 05:48

Also, you'll need to append "\r" at end of line to indicate "carriage return" and do next print at beginning of current line

3Not if he's simply planning to print more at the end of the current line. He can use puts for the last print to complete the line. This is useful when printing a list of varying (yet short) length, for example. – BobDoolittle Sep 22 '15 at 00:06

$stdout.sync = true
100.times do
print "."
sleep 1
end
