You want "man 1 test", which will tell you about:
if [ \( $numb -gt 3 \) -a \( $numb -lt 10 \) ]; then
echo "hello"
fi
That's because /bin/[ is a link to /bin/test, and not part of the
"if" statement. "if" just evaluates it's argument, and does the
"then" part if the result is true (0). In this case, the argument
is "[ $numb -eq 3 ]", which is equivelant to "test $numb -eq 3".
