What is wrong with the following command string: ls /etc/hosts>listofhostfile?
a. Nothing is wrong with the command.
b. The file descriptor was not declared; unless 1 for stdout or 2 for stderr is indicated, the command will fail.
c. The ls command is one of the commands that cannot be used with redirection. You must use | to pipe instead.
d. The file listofhostfile will always only contain stderr because a file descriptor was not declared.
