Wow, that's overkill. You don't need the -F ' ' options to awk, since
that's the default. You don't need tr to remove the space because
awk will happily not print one if you omit the comma.

And you don't need awk in the first place because date will handle
the desired output directly if you just ask it to.

date -d 'next month' +%b%Y

Note, I'm not sure that's robust if you call it on, say, the 31st of the month
if the next month doesn't have 31 days. It might give you two months from now.
Read the man page for date for further enlightenment.
