UUPOLL(8C) — NEWS-OS Programmer’s Manual

NAME

uupoll − poll a remote UUCP site

uupoll [ −ggrade ] [ −n ] system

uupoll is used to force a poll of a remote system. It queues a null job for the remote system and then invokes uucico(8C).

The following options are available:

−ggrade Only send jobs of grade grade or higher on this call.

−n Queue the null job, but do not invoke uucico.

uupoll is usually run by cron(5) or by a user who wants to hurry a job along. A typical entry in crontab could be:

00,8,16∗∗∗/usr/bin/uupoll ihnp4
04,12,20∗∗∗/usr/bin/uupoll ucbvax

This will poll ihnp4 at midnight, 0800, and 1600, and ucbvax at 0400, noon, and 2000.

If the local machine is already running uucico every hour and has a limited number of outgoing modems, a more elegant approach might be:

00,8,16∗∗∗/usr/bin/uupoll −n ihnp4
04,12,20∗∗∗/usr/bin/uupoll −n ucbvax
5∗ ∗∗∗/usr/lib/uucp/uucico −r1

This will queue null jobs for the remote sites at the top of hour; they will be processed by uucico when it runs five minutes later.
