What Others Think

That command doesn't work. As currently displayed, it attempts to execute the result of the math (eg a number) or it runs the echo command. (This will lead to several '#: command not found.) This would be a better command to do what you are attempting: if [[ $(($RANDOM%6)) == 0 ]] then; echo 'hello, world!'; fi

Oops, the ";" goes after the "]]". Eliminate ";" after "then".

On zsh and bash 4.0 (2 sh I have) this return 0 or 1: (($RANDOM%6)); echo $? And this complains about non-existing method 4 (or 5, or 3 - this seems to be completly random ;) ) $(($RANDOM%6))

perl -e '$i[0]="Hello world"; print $i[int(rand(6))], "\n";'
