I don't see anything wrong with what you have above, but I want to caution
you about using this as a test for anything important.  Consider this:

I create a shell script called "whoami" and place it in $HOME/bin.
My new-and-improved "whoami" script contains the following:

#!/bin/sh
echo root

Then I change my $PATH, like this:
PATH=$HOME/bin:$PATH

Now when I run your script, the test for whoami will return root.  Most
likely your script would require root to run whatever following commands
you might have and that you added this line just to notify people that
they can't successfully procede.  In any case, be careful when you're
writing shell scripts.
