WM-LICENSE(1) WM-LICENSE(1)
NAME
license - display and confirm licence terms
SYNOPSIS
wm/license
DESCRIPTION
License displays the contents of the system licence file
/licencedb/LICENCE and prompts the user to accept or reject
the terms. If the licence file does not exist the command
exits without displaying anything.
If the user accepts the terms of the licence then a file is
created in the /licencedb directory to indicate acceptance.
The filename is derived from the current user and host name
as read from /dev/user and /dev/sysname respectively.
The acceptance file contains the text:
Username@Hostname Timestamp
where Timestamp is the text read from the file /dev/time at
the time of writing the acceptance file.
The name of the acceptance file is a 16 digit hexadecimal
number. The numeric value of the filename is formed as a
64-bit value with userval in the high-order 32 bits and
hostval in the low-order 32 bits, where userval and hostval
are calculated from the username and hostname text by the
following expression: val = SUM(text[n] x 3^(len-n)), where
len is the length of the text and text[n] is the unicode
code-point of the nth character in the string (starting at
1).
