Scheduled download on Windows 7 systems
To perform scheduled downloads on a Windows 7 system, you create
a .bat file containing the download command as described above, then
create scheduled task that runs the .bat file.
You can place the .bat file wherever is convenient. The log repository
directory is a reasonable choice.
To create the scheduled task, select the Create Task… option from the
Actions supanel of the Task Scheduler control panel. (The Task Sched-
uler is one of the Administration control panels.) You set the download
times by creating a Trigger from the Triggers tab. Set the Trigger to
begin the task on a daily schedule. In the advanced settings section,
set the task to repeat every hour for the full duration of the day. If you
set the option to stop the task if it runs longer than 55 minutes, it will
keep a slow or stalled download from overlapping with the next sched-
uled download.
Scheduled download on UNIX systems
On UNIX systems, you can perform scheduled downloads using cron.
In general terms, you create a shell file containing the download com-
mand and a crontab file that specifies the task and schedule, and then
install the task using the crontab utility. The following notes provide
additional detail.
There is considerable variability among UNIX systems, so you’ll need to
consult local documentation in addition to these notes.
In the crontab file, tasks are specified by lines that have a sequence of
tab-separated fields:
minute (0-59)
hour (0-23)
day of month (1-31)
month (1-12, or names)
day of week (0-7, or names)
command name
