这是`at`命令执行任务时的提示信息,它告诉您:
1. `at`命令将使用`/bin/sh`来执行您指定的命令。`/bin/sh`是Linux/Unix系统中的默认shell程序,它提供了一种解释和执行命令的方式。
2. `at`命令将在指定的时间(Fri May 26 20:50:00 2023)执行任务。在这个时间到来之前,任务将被放置在`at`队列中等待执行。
如果您想在执行命令时使用其他shell程序,可以在命令前添加shell程序的路径,例如:
```
echo "Hello World" | /bin/bash
```
这将使用`/bin/bash`来解释和执行`echo "Hello World"`命令。
