I would have written [[:space:]]* instead of [[:space:]]+ to handle
potentially missing space, at least after the comma but also before the
comma to avoid surprises for new names in the future.
Furthermore <space>|<tab> alone would be [[:blank:]]* but as you prefer.

grep ... > /dev/null would be grep -q which is mandated by POSIX since
at least SUSv2 so can be used safely since quite some time now.

Instead of the redundant 'true' calls, i'd usually write :
E.g.
if grep -q ... ; then :
else echo "nah"; exit 1
fi

Which could be shortened to
if ! grep -q ...
then
  echo "nah"
  exit 1
fi

to avoid any questions about an empty arm in the first place.

ISTM you only set the expected flags in the switch so i would have
set only that variable and have grepped only once after the switch for
brevity.

Either way, thanks for not using grep -P :)
thanks,
