format-check.sh uses non-existent command "NOT"

Line 7 in e73e472

if NOT type $CLANG_FORMAT > /dev/null 2>&1; then

I assume without knowing exactly that the author of that commit has NOT as an alias to ! in his .bashrc.
Apparently they tested it locally on their machine (where it worked) and then commited the NOT in the remote repo.

alias NOT='!'

if NOT false; then
    echo "the if condition is true."
fi

This is the only explanation I can see plausible. Of course the NOT must be removed and replaced with a proper !.

replaced with a proper !.

Most likely
