我剛剛安排了一個休眠命令：
at 13:00 shutdown /h
有沒有指令可以中止這個預定的操作？
shutdown /a沒用，它說沒有計劃的關閉。At 12:59 shutdown /a對於中止來說效果不佳At 13:00 shutdown /h
答案1
就我而言，atq列出所有用at.範例輸出：
atq
2 Fri May 1 06:00:00 2020 a root
1 Fri May 1 05:00:00 2020 a root
如果您需要更多資訊來了解哪個作業是什麼，您可以執行at -cjobid 來查看將為此作業 ID 執行的命令。例如：
at -c 1
#!/bin/sh
umask 22
LANG=bg_BG.UTF-8; export LANG
SUDO_GID=1000; export SUDO_GID
...
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin; export PATH
...
ls
（省略了一些輸出，並用 代替...）
然後atrm加上作業 ID 以刪除某個預定作業。範例（成功時沒有輸出）：
atrm 1
答案2
Shutdown /a 僅在使用命令安排關閉後才起作用
因此等待關閉事件觸發然後執行 shutdown /a
所以如果你在 13.01 運行它就會起作用
答案3
有沒有指令可以中止這個預定的操作？
at 13:00 shutdown /h
您可以at自行運行以列出計劃的作業。例子：
F:\test>at 13:00 echo "hello"
Added a new job with job ID = 1
F:\test>at
Status ID Day Time Command Line
---------------------------------------------------------------------
1 Tomorrow 13:00 echo hello
這將傳回計劃作業的列表，以及ID每個作業的列表。
若要刪除預定作業：
at ID /delete
例子：
F:\test>at 13:00 echo "hello"
Added a new job with job ID = 1
F:\test>at
Status ID Day Time Command Line
-------------------------------------------------------------------------------
1 Tomorrow 13:00 echo hello
F:\test>at 1 /delete
F:\test>at
There are no entries in the list.
若要刪除排程作業，請使用schtasks：
schtasks /delete /tn At{ID}
{ID}任務ID在哪裡at。
例子：
F:\test>schtasks /delete /tn At1
WARNING: Are you sure you want to remove the task "At1" (Y/N)? y
SUCCESS: The scheduled task "At1" was successfully deleted.
刪除全部預定工作：
at /delete /yes
使用時
F:\test>at /?
