Each entry consists of three colon separated fields. The first field
|
|
is a comma separated list of tty devices, or an asterisk to indicate
|
|
that all tty devices are matched by this entry. The second field is a
|
|
comma separated list of user names, or an asterisk to indicated that
|
|
all user names are matched by this entry. The third field is a comma
|
|
separated list of permitted access times.
|
|
</para>
|
|
|
|
<para>
|
|
Each access time entry consists of zero or more days of the week,
|

abbreviated <emphasis>Su</emphasis>, <emphasis>Mo</emphasis>,

<emphasis>Tu</emphasis>, <emphasis>We</emphasis>,
|
|
<emphasis>Th</emphasis>, <emphasis>Fr</emphasis>, and
|
|
<emphasis>Sa</emphasis>, followed by a pair of times separated by a
|
|
hyphen. The abbreviation <emphasis>Wk</emphasis> may be used to
|
|
represent Monday thru Friday, and <emphasis>Al</emphasis> may be used
|
|
to indicate every day. If no days are given, <emphasis>Al</emphasis>
|

is assumed.
