The most common method of silencing an error in Linux is to redirect than error to
/dev/null which is like the trash bucket of the system. We can do that by including
2> /dev/null to the end of a command.
Create Code That Will Produce Error
ls: a_fake_directory/: No such file or directory
Notice that we aren’t silencing so much as redirecting into
/dev/null. This is like sending the error into a black hole.
ls a_fake_directory/ 2> /dev/null
