Question

我有这个bash脚本：

#!/bin/bash


inotifywait -m -e close_write --exclude '\*.sw??$' . |
#adding --format %f does not work for some reason
while read dir ev file; do
        cp ./"$file" zinot/"$file"
done
~

现在，我如何让它执行相同的操作，还可以通过将文件名写入日志文件来处理删除操作？有点像？

#!/bin/bash


inotifywait -m -e close_write --exclude '\*.sw??$' . |
#adding --format %f does not work for some reason
while read dir ev file; do
        # if DELETE, append $file to /inotify.log
        # else
        cp ./"$file" zinot/"$file"
done
~

编辑：

通过查看生成的消息，我发现只要文件关闭，inotifywait就会生成CLOSE_WRITE,CLOSE。这就是我现在正在检查我的代码。我还尝试检查DELETE，但由于某种原因，该部分代码无效。看看：

#!/bin/bash

fromdir=/path/to/directory/
inotifywait -m -e close_write,delete --exclude '\*.sw??$' "$fromdir" |
while read dir ev file; do
        if [ "$ev" == 'CLOSE_WRITE,CLOSE' ]
        then
                # copy entire file to /root/zinot/ - WORKS!
                cp "$fromdir""$file" /root/zinot/"$file"
        elif [ "$ev" == 'DELETE' ]
        then
                # trying this without echo does not work, but with echo it does!
                echo "$file" >> /root/zinot.txt
        else
                # never saw this error message pop up, which makes sense.
                echo Could not perform action on "$ev"
        fi

done

在目录中，我做touch zzzhey.txt。文件已复制。我执行vim zzzhey.txt并复制文件更改。我执行rm zzzhey.txt并将文件名添加到我的日志文件zinot.txt中。真棒！

您需要将-e delete添加到您的监视器，否则DELETE事件将不会传递给循环。然后为处理事件的循环添加一个条件。这样的事情应该做：

#!/bin/bash

inotifywait -m -e delete -e close_write --exclude '\*.sw??$' . |
while read dir ev file; do
  if [ "$ev" = "DELETE" ]; then
    echo "$file" >> /inotify.log
  else
    cp ./"$file" zinot/"$file"
  fi
done

inotifywait的Bash脚本 - 如何将删除写入日志文件，以及cp close_writes？
