How to su into the account name arch with some kind of escape method?

Solution

  • I think the confusion is because you could login as root using

    su - # There are no options in this case and the default login is root

    But you're not supposed to do

    su -arch #Anything the follows is an option

    Since a is not a valid option you got an error

    The right way could be anyone among the below

    su arch 
su - arch # mind the space
su -- arch # The -- marks the end of options, gives way for non-options arguments
