I would like to record programmes from an online radio stream. For this purpose I would like to find a program for Windows, which supports timed execution of jobs, similarly like crontab on Linux, and the jobs can be added from simple text file - similarly to crontab - or as a JSON file, etc.

Or equivalently a multimedia program - like VLC, ffmpeg, etc. - which supports recording streams beginning at a given time, and stopping the recording process after a certain time elapsed. Maybe with a plugin.

That program is called at.exe on Windows, and it runs as a commandline app, inside the batch/MS-DOS shell. On Windows at.exe does the same things as cron on Unix, not as at on unix.

The Wikipedia article about at highlights the differences - with screenshots, command options and their syntax, etc. (Scroll down a bit on the article's page.)

The requirements to use at.exe with .bat files is a bit awkward. But you could put a single command inside that bat file, a call to your custom script (in Powershell, Perl, Python...).

  • Curiously, the at command is missing from SS64.com: ss64.com/nt Commented Jul 9, 2022 at 21:11
  • It's not at, it is at.exe. Not a built-in shell command. -- If it is no longer installed on newer versions of Windows: As far as I remember, some older programs can be installed from so-called "Resource Kits", big collections of optional files and programs, provided by Microsoft. I don't know how those are called today.

  • Right, but SS64 lists external commands as well as internal ones. Robocopy (robocopy.exe), takeown (takeown.exe), and tracert (tracert.exe) are good examples. Commented Jul 11, 2022 at 11:07

    Fair enough. I didn't notice that. Just skimmed the A, B, C entries.
