如何使用inotifywait监视文件夹而不是文件夹中的文件 [英] How to use inotifywait to watch files within folder instead of folder

问题描述

我想使用inotifyway监视文件夹中新创建或移动的文件，但仅监视文件.

I want to use inotifyway to monitor newly created or moved file within a folder But only the files.

假设我的文件夹名为"watched_folder_test"，文件名为"toto.txt".如果我使用mv命令将文件移至watched_folder_test，则会收到我想要的通知

Let's say my folder is name "watched_folder_test" and I have a file name "toto.txt". If I use the mv command to move the file to the watched_folder_test I got notify that I want

比方说，在watched_folder_test中，我有一个名为foo的文件夹，并创建了一个文件名'bar.txt".我收到了想要的通知.

Let's say inside the watched_folder_test I have a folder named foo and I create a file name 'bar.txt". I got the notification that I want.

但这是我的问题.如果我在watched_folder_test之外有一个文件夹名称foo 我里面有一个文件名bar.txt(foo/bar.txt)，然后将整个文件夹移到watched_folder_test中.我只收到创建foo的通知！与bar.txt无关.但是，我并不真正关心foo，我只想了解"bar.txt"

But here is my issue. If I have a folder name foo outside of watched_folder_test and I have a file name bar.txt inside it ( foo/bar.txt ) and I move that entire folder inside watched_folder_test. I only get the notification that foo is created ! Nothing about bar.txt. However, I don't really care about foo, I only want to know about "bar.txt"

到目前为止，这是我的代码

here is my code so far

#!/bin/bash                                                                                          

inotifywait -mr /home/romain/depot/watched_folder_test -e create -e moved_to |
    while read path action file; do
        echo "The file '$file' appeared in directory '$path' via '$action'"
        for ac in $action
        do
            isdir=`echo $ac | grep 'ISDIR'`
            if [ $? == 0 ]
            then
                echo "It's a folder"
            else
                echo "It's a file"
            fi
        done
    done

如何获取有关新移动文件夹中的每个文件的通知，而不是创建文件夹本身的通知?

How can I get notify about every file that within a newly moved folder instead of the creation of the folder itself ?

推荐答案

我不是inotifytools(包括inotifywait)的粉丝.我建议用户在使用它时要格外小心，因为在移入(移入和移入)目录上进行递归监视时，这是完全错误的.

I'm not a fan of inotifytools which includes inotifywait. I would advise users to exercise utmost caution while using it because it is totally erroneous when it comes to recursive watch on moved(from and to) directories.

只是为了阐明我的观点，让我们考虑一下您当前遇到的一种相关情况；目录移动.说，我们正在看/foo/bar:

Just to get my point across, let's consider a relevant situation that you currently have; dir moves. Say, we are watching /foo/bar:

在mv /foo/bar /choo/tar上，即使移出(重命名?)/foo/bar到/choo/tar，它将继续错误地将/choo/tar上的事件报告为/foo/bar.这是无法接受的！它不应继续监视从根监视路径移出的目录.而且，更糟的是，它继续使用不存在的陈旧路径来报告它.

On mv /foo/bar /choo/tar, even after moving out(rename?) /foo/bar to /choo/tar, it will continue to report events on /choo/tar as /foo/bar erroneously. This is unacceptable! It should not continue to watch a dir that was moved out of the root watch path. And, to make it worse, it continues to report it with a stale path that doesn't exist.

此外，为什么将move事件报告为create?太离谱了！ move与create完全不同！ move是move，必须将其报告为move.可惜的是inotifytools如此流行，而毫无戒心的用户却没有意识到它的谬误.

Besides, why is a move event reported as create? Outrageous! A move is totally different from a create! A move is a move, it must be reported as a move. It's a shame that inotifytools is hugely popular and unsuspecting users are unaware of its fallacies.

现在我已经消除了挫败感(尽管这是相关的)，让我们来帮助解决您的问题.

Now that I have vented out the frustration(which is relevant though), let's help fix your situation.

不同于inotifytools，fluffy 忠实报告事件！

Unlike inotifytools, fluffy faithfully reports the events!

我希望这个例子足以使您为您的用例做好准备.干杯！

I hope this example will be sufficient for you to step it up for your use case. Cheers!
