Windows NT

With Windows Vista, Windows 7, Windows 8, and newer versions, the at command is deprecated; use the schtasks command instead.

At syntax

The AT command schedules commands and programs to run on a computer at a specified time and date. The Schedule service must be running to use the AT command.

AT [\\computername] [ [id] [/DELETE] | /DELETE [/YES]] AT [\\computername] time [/INTERACTIVE] [ /EVERY:date[,...] | /NEXT:date[,...]] "command"

\\computername	Specifies a remote computer. Commands are scheduled on the local computer if this parameter is omitted.
id	Is an identification number assigned to a scheduled command.
/delete	Cancels a scheduled command. If id is omitted, all the scheduled commands on the computer are canceled.
/yes	Used with cancel all jobs command when no further confirmation is desired.
time	Specifies the time when command is to run.
/interactive	Allows the job to interact with the desktop of the user who is logged on at the time the job runs.
/every:date[,...]	Runs the command on each specified day(s) of the week or month. If date is omitted, the current day of the month is assumed.
/next:date[,...]	Runs the specified command on the next occurrence of the day (for example, next Thursday). If date is omitted, the current day of the month is assumed.
"command"	Is the Windows NT command, or batch program to run.

At examples

at 6:50PM "c:\winnt\task.bat"

Performing this command would run the task.bat file at 6:50PM today unless the task is scheduled after the time specified. Because the /interactive switch is not in the command, this batch file will be executed in the background.

at 6:50PM /interactive c:\winnt\beep.bat

Runs the beep.bat batch file at 6:50PM with the ability for the user to interact with the batch file.

at 1 /delete

Deletes the at ID 1.

at /delete /yes

Delete all AT IDs.
