Android 如何在shell脚本中睡觉？

我尝试在shell脚本中添加sleep命令。但当我运行sh文件时，它显示“语法错误：无效参数”2。但是，当我直接发送到提示控制台时，sleep命令可以正常工作 .sh文件脚本，如下所示：

“#！/bin/sh
sendevent/dev/input/event23 57 11
sendevent/dev/input/event2 1 330 1
sendevent/dev/input/event2 1 325 1
sendevent/dev/input/event23 53 1343
sendevent/dev/input/event23 54 2403
sendevent/dev/input/event2 3 48 3
sendevent/dev/input/event2 0 0
sendevent/dev/input/event2 3 53 1341
sendevent/dev/input/event23 54 2401
sendevent/dev/input/event2 0 0
sendevent/dev/input/event2 3 57-1
sendevent/dev/input/event2 1 330 0
sendevent/dev/input/event2 1 325 0
sendevent/dev/input/event2 0 0
睡眠2
sendevent/dev/input/event2 3 57 12
sendevent/dev/input/event2 1 330 1
sendevent/dev/input/event2 1 325 1
sendevent/dev/input/event2 3 53 1004
sendevent/dev/input/event23 54 924
sendevent/dev/input/event2 0 0
sendevent/dev/input/event2 3 57-1
sendevent/dev/input/event2 1 330 0
sendevent/dev/input/event2 1 325 0
sendevent/dev/input/event2 0 0

大家能帮我检查一下吗？

谁想知道更新。答案很简单，只需添加“；“在Sleep命令的末尾

sendevent /dev/input/event2 0 0 0 Sleep; sendevent/dev/input/event2 0 0 睡觉
