You've very nearly got it right, but you're missing a critical part
of the shell syntax you need.
What you've told touch to do, above, is to accept on its standard input
the name of the file to touch.
But many commands don't work that way, they want the file name on
their commandline.
You can do that in any (AFAIK) Unix shell (including bash) by enclosing
the command in (what is often called) backtics, this character: `
It's NOT the apostrophe ('), but its approximate mirror image.
This takes the standard output of whatever is enclosed inside it
and substitutes it into the commandline of the preceding command.
So, to do what you want, you should do:
touch `date +%m_%b_%y.out`
