A shell script developer knows that the date $+\%$A command gives the current local weekday name $($Sunday$,$ Monday, Tuesday, $...).$

Which of the following commands will copy the authentication log file, $/$var$/$log$/$auth$.$log$,$ to a new file with a filename that includes the current local weekday name?

answer

cp $/$var$/$log$/$auth$.$log ~$/$auth$$($date $+\%$A$).$log

cp $/$var$/$log$/$auth$.$log ~$/$auth$$\{$date $+\%$A$\}.$log

tee $/$var$/$log$/$auth$.$log $>$ date $+\%$A $-$log

xargs $/$var$/$log$/$auth$.$log ~$/$auth$$($date $+\%$A$).$log
