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 be run. |
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. at Typing at alone will display each of the scheduled tasks, their status, id, scheduled time, and command as shown below. As you can see if an error occurs with the at process, the status will display an Error.
