                     12: The COHERENT system normally invokes  login as part of the log in
                     13: sequence on  an unused terminal.  The user  may also invoke login
                     14: directly from the shell sh, usually to change to a different user
                     15: name.  If  username is not  present, login prompts  the user.  If
                     16: the account has a password, login asks for it.
                     17: 
                     18: If  the user  logs  in successfully,  login then  reads the  file
                     19: /etc/motd (which holds the ``message of the day'') and prints its
                     20: contents  on  the screen,   then  notifies the  user  if mail  is
                     21: waiting to  be read.  It  then sets the working  directory to the
                     22: user's base  directory and sets the user id  and group id, trans-
                     23: fers ownership of the tty to  the user, and updates the login ac-
                     24: counting   file.   Finally,   if  a   program  is   specified  in
                     25: /etc/passwd, login  reads /etc/profile for  lines beginning ``ex-
                     26: port'', inserts  the remainder of the  line into the environment,
                     27: then  executes the  specified program.  If  the program  field is
                     28: blank,  login  executes   sh,  which  executes  the  contents  of
                     29: $HOME/.profile if it is present.
                     30: 
                     31: From the shell, a user may log in by typing login or by typing an
                     32: end of file (normally <ctrl-D>) to terminate the previous shell.
                     33: 
                     34: When the superuser rroooott logs in, login sets HHOOMMEE to `/' and reads
                     35: the file /.profile should one exist.
