       users  - print the user names of users currently logged in
       to the current host

       users [FILE]
       users {--help,--version}

       This manual page  documents  the  GNU  version  of  users.
       users  prints  on  a single line a blank-separated list of
       user names of users currently logged  in  to  the  current
       host.   Each  output user name corresponds to a login ses-
       sion, so if a user has more than one login  session,  that
       user's  name  will  appear the same number of times in the
       output.  With no file argument, users extracts its  infor-
       mation  from  the  file /etc/utmp .  If a file argument is
       given, users uses that file instead.  A common  choice  is
       /etc/wtmp .
