At Command Availability
The at command is available from within the Command Prompt in many Windows operating systems including Windows 7, Windows Vista, Windows XP, and some older versions of Windows as well. This command has been deprecated beginning in Windows 8. Microsoft recommends using the feature-rich schtasks command instead. The availability of at command switches may differ somewhat from operating system to operating system.
At Command Syntax
This is the proper syntax of the at command: at \computername /interactive | /every:date,…/next:date,… In this example, the at command is used to schedule the execution of the bkprtn.bat batch file on the computer named prodserver at 11:45 p.m. on the first, fourth, eighth, 12th, 16th, 20th, 24th, and 28th day of each month. Here, the scheduled command with the id of 1 is deleted.
