A. A. NT comes with a powerful built in scheduling tool, the at command, however it is not really suitable for running a command every 5 minutes, to do this you would have to submit hundreds of at jobs to run at certain times of the day. There are a number of tools supplied with the Windows NT Resource Kit which will help.
The first is called sleep.exe, and is user to set a command file to wait
for n seconds (like the timeout command), and its usage is simply
sleep 300
which would make the batch file pause for 5 minutes, so if you wanted a
command file/program to run every 5 minutes you could write a batch file
with the following (name run5.bat)
<program name>
sleep 300
run5
There are a number of problems with this approach, the command session has to stay open, and the 5 minutes does not start until the program has closed (however this can be solved by running the program in a separate thread by putting the word "start" in front of the program, e.g. start <program>).
Another program is called SOON.EXE and this schedules a task to run in n
seconds from now, to use soon the scheduler service has to be running
(start - settings - control panel - services). Again you could create a
batch file to use it (runsoon.cmd)
soon 300 runsoon.cmd
notepad.exe
Run the command file using the at command or soon, e.g. from the command
line
soon 300 runsoon.cmd
to get it started
Once the SOON is scheduled to run, if you wanted to stop it you would use the AT command to get a list of current scheduled jobs
C:\>at
Status ID Day Time Command Line
-------------------------------------------------------------------------------
0 Today 9:04 AM runsoon.cmd
Once its ID is known it can be stopped using
C:\>at \[\\computer name\] <ID> /delete
e.g. C:\>at 0 /delete
