How to tell if a DOS batch script is being run by task scheduler?

Question

How can a DOS Batch command file determine if it is being run by Task Scheduler?

Answer 1

If you control both the batch and the scheduled task, you could configure it to use a parameter.

Example - in the Scheduled Task, on the Action, you could define a parameter like: /ScheduledTask

In the batch file, you could check for the existence of the command-line parameter:

if /i %1==/ScheduledTask set RUN_BY_TASK_SCHEDULER=1

Answer 2

maybe if the task was scheduled with another account, local or domain.

Inserting an IF based on enviroment variables like %userdomain% or %username%
