NAME

     passwd - password file



DESCRIPTION

     Passwd contains for each user the following information:



          name (login name, contains no upper case)

          encrypted password

          numerical user ID

          numerical group ID (for now, always 1)

          GCOS job number, box number, optional GCOS user-id

          initial working directory

          program to use as Shell



     This is an ASCII file.  Each field within each user's  entry

     is  separated  from  the next by a colon.  The GCOS field is

     used only when communicating with that system, and in  other

     installations  can  contain  any  desired information.  Each

     user is separated from the  next  by  a  new-line.   If  the

     password  field  is  null,  no  password is demanded; if the

     Shell field is null, the Shell itself is used.



     This  file  resides  in  directory  /etc.   Because  of  the

     encrypted  passwords,  it  can  and  does  have general read

     permission and can be used, for example,  to  map  numerical

     user ID's to names.
