Inotifywait将不会运行

Question

inotifwait不会运行命令

输出"Setting up watches. Watches established“，脚本退出

 #!/bin/bash

while $(inotifywait -e  modify,close_write /home/centos/test.txt);
do
  touch /home/centos/log.txt
done

但当我修改test.txt时，并未创建log.txt

我试过这个版本：

#!/bin/bash

inotifywait -e modify,close_write /home/centos/test.txt |
while read output; do
  touch /home/centos/log.txt;
done

我也试过了：

inotifywait -e modify,close_write /home/centos/test.txt |
while read -r filename event; do
  echo "test"        # or "./$filename"
done

通过添加-m /folder解决了这个问题
