Schedule a job from the Windows command line?

"Windows also has an ""at job"". Albeit the syntax is a little different.

C:\Documents and Settings\Administrator>at /?
The AT command schedules commands and programs to run on a computer at
a specified time and date. The Schedule service must be running to use
the AT command.

AT [\\computername] [ [id] [/DELETE] | /DELETE [/YES]]
AT [\\computername] time [/INTERACTIVE]
[ /EVERY:date[,...] | /NEXT:date[,...]] ""command""

\\computername Specifies a remote computer. Commands are scheduled on the
local computer if this parameter is omitted.
id Is an identification number assigned to a scheduled
command.
/delete Cancels a scheduled command. If id is omitted, all the
scheduled commands on the computer are canceled.
/yes Used with cancel all jobs command when no further
confirmation is desired.
time Specifies the time when command is to run.
/interactive Allows the job to interact with the desktop of the user
who is logged on at the time the job runs.
/every:date[,...] Runs the command on each specified day(s) of the week or
month. If date is omitted, the current day of the month
is assumed.
/next:date[,...] Runs the specified command on the next occurrence of the
day (for example, next Thursday). If date is omitted, the
current day of the month is assumed.
""command"" Is the Windows NT command, or batch program to be run.

Example:

at 9:00 /interactive notepad.exe

This will cause Notepad to interactively open for the user at 9:00 in the morning."

"Write a Windows shell script to do it using a sleep program for delay:

@echo off

:loop
someprogram args
sleep 900
if somecondition goto loop

Run it in a shell window of its own. Configure cmd.exe to run on power up with this script. sleep sleeps for a number of seconds:

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <Windows.h>

int main(int argc, char* argv[])
{
int n = atoi(argv[1]);

Sleep(n * 1000);

return 0;
}"
