PASSWD(M)                XENIX System V                 PASSWD(M)



     Name
          passwd - The password file.

     Description
          Passwd contains the following information for each user:

               -Login name

               -Encrypted password

               -Numerical user ID

               -Numerical group ID

               -Comment

               -Initial working directory

               -Program to use as shell

          Refer to finger(C) for information in the required format of
          the comment field for finger(C) to display the information.
          Each user is separated from the next by a newline.  If the
          password field is null, no password is demanded; if the
          shell field is null, sh(C) is used.

          This file resides in the directory /etc.  Because the
          passwords are encrypted, the file has general read
          permission and can be used, for example, to map numerical
          user IDs to names.

          The encrypted password consists of 13 characters chosen from
          a 64-character alphabet (., /, 0-9, A-Z, a-z), except when
          the password is null, in which case the encrypted password
          is also null. Password aging is in effect for a particular
          user if his encrypted password in the password file is
          followed by a comma and a nonnull string of characters from
          the above alphabet. (Such a string must be introduced by the
          super-user.) The first character of the age denotes the
          maximum number of weeks for which a password is valid.  A
          user who attempts to log in after his password has expired
          will be forced to supply a new one.  The next character
          denotes the minimum period in weeks which must expire before
          the password may be changed. The remaining characters define
          the week (counted from the beginning of 1970) when the
          password was last changed. (A null string is equivalent to
          zero.) The first and second characters must have numerical
          values in the range 0-63, where the dot (.) is equal to 0
          and lowercase z is equal to 63.  If the numerical value of
          both characters is 0, the user will be forced to change his
          password the next time he logs in. If the second character
          is greater than the first, only the super-user will be able
