DOS疑难解答 & 问题讨论（解答室） » Why can't %username% be displayed in the at command

Under XP I made an at task to call test.bat and run it in the background. One line in test.bat is echo %username%>>D:\list.txt. After test.bat runs at the scheduled time, the current logged-in username does not appear in list.txt, and instead it shows "ECHO is off." If I run test.bat by itself, it displays correctly. What is going on? [ Last edited by namejm on 2006-4-22 at 23:41 ]

The at command uses the SYSTEM account, which does not have the %username% variable. You can use at xx:xx /interactive cmd to start cmd, then use set to check.
