In linux, in shell scripts, conditions for if statement can be checked using the test command, as below

if test 4 -gt 2; then
   echo "4 is bigger than 2"
fi

But there is a more syntatically elegent/common way to write the above, what is it? And think of the real point behind this buboflash question!

^^ really what this question is demonstrating is that the if statement has as its condition, just some command that either returns success (0) or fail (non-zero) error code and that determines whether the if clause is executed! And the "[ ]" syntax is just a better looking replacement for the test command!
