Can someone enlighten me why this:

wget --quiet --no-check-certificate ttps://flub.githubusercontent.com/jodrell/jwhois/master/example/jwhois.conf ; echo $?

returns this: 0

When wget --no-quiet says this:

wget --no-quiet --no-check-certificate ttps://flub.githubusercontent.com/jodrell/jwhois/master/example/jwhois.conf ; echo $?

ttps://flub.githubusercontent.com/jodrell/jwhois/master/example/jwhois.conf: Unsupported scheme `ttps'.

0

Is not an unsupported scheme an error in much the same fashion as an invalid URI? Should it not return an non-zero value in '$?' ?

wget https://flub.githubusercontent.com/jodrell/jwhois/master/example/jwhois.conf ; echo $?
