Less painful ways to write scheduled tasks for the Windows at command.
- Use absolute paths to reference files or folder because
atstarts in a default folder, not the folder you are currently using.
- Use caret (^) to escape the redirection characters so that you can combine the output (stdout) and error (stderr) streams to a file.
Here's an example that combines those tips:
at 12:00 C:\Temp\Test.cmd ^> C:\Temp\Test.log 2^>^&1.
It is also be useful to dump the
at command's environment variables so that you can check if the variables are set correctly (e.g.
at 12:00 cmd /c set ^> D:\Temp\Env.txt.
2013/12/10: With Task Scheduler, you don't need to use the caret to escape the cmd metacharacters, i.e. Program =
cmd and Arguments =
/c C:\Temp\Test.cmd > C:\Temp\Test.log 2>&1.
