.SH "描述"
|
|
.PP
|
|
\fIporttime\fR
|
|

|
|
.PP
|
|

|
|
.PP
|
|
Each access time entry consists of zero or more days of the week, abbreviated
|
|
\fISu\fR,
|
|
\fIMo\fR,
|
|
\fITu\fR,
|
|
\fIWe\fR,
|
|
\fITh\fR,
|
|
\fIFr\fR, and
|
|
\fISa\fR, followed by a pair of times separated by a hyphen\&. The abbreviation
|
|
\fIWk\fR
|
|
may be used to represent Monday thru Friday, and
|
|
\fIAl\fR
|
|
may be used to indicate every day\&. If no days are given,
|
|
\fIAl\fR
|
|
is assumed\&.
