我已经改进了用户 konsolebox 的这个“FolderWatcher 脚本”（来自下面的答案：https ://stackoverflow.com/a/18597233/2095175 ）我已经添加了这些行来自动移动我的正确文件夹中的每种文件系统（例如 /Docs 文件夹中的 pdf、/Picture 中的图像和 /Videos 中的视频文件）

extension=${ADDED##*.}
if [ "$extension" = "xz" ] || [ "$extension" = "zip" ] || [ "$extension" = "gz" ] || [ "$extension" = "bz2" ] || [ "$extension" = "7z" ]; then
open $ADDED
fi
if [ "$extension" = "pdf" ] || [ "$extension" = "txt" ] || [ "$extension" = "odt" ] || [ "$extension" = "doc" ] ; then
mv "$ADDED" /boot/home/Docs
alert --idea " $ADDED moved to /boot/home/Docs"
open /boot/home/Docs
fi
if [ "$extension" = "jpg" ] || [ "$extension" = "png" ] || [ "$extension" = "gif" ]; then
mv "$ADDED" /boot/home/Media/Images
alert --idea " $ADDED moved to /boot/home/Media/Images"
open /boot/home/Media/Images
fi
if [ "$extension" = "flv" ] || [ "$extension" = "avi" ] || [ "$extension" = "mp4" ] || [ "$extension" = "mpg" ]; then
mv "$ADDED" /boot/home/Media/Video
alert --idea " $ADDED moved to /boot/home/Media/Video"
open /boot/home/Media/Video
fi

原始问题：

我有以下脚本不断检查文件夹的内容，并在插入新文件和/或删除新文件时提醒我。按预期完美运行。但不检查主文件夹中的子文件夹（ folder=$(cat /boot/home/FolderWatcher_pref.txt) ）例如，如果我从主文件夹中插入/删除文件，我会收到警报，但如果我插入/删除文件在“$folder”的子文件夹中，脚本无法提醒我。我可以在此脚本中更改或添加什么来满足此需求？

我在 Haiku OS 上，所以像“alert”这样的命令是 Haiku 特有的。

为什么不能使用inotifywait或inotifywatch？您可以使用-r标志使其递归。看看inotify-tools。
您可能也对incron感兴趣。

我最终进行了自己的修改，但是这个可以工作并且不再使用临时文件。它使用find和process substitution。

#!/bin/bash

[ -n "$BASH_VERSION" ] && [[ BASH_VERSINFO -ge 3 ]] || {
    echo "You need bash version 3.0 or newer to run this script." >&2
    exit 1
}

shopt -s extglob

FOLDER=$(</boot/home/FolderWatcher_pref.txt)
REMOVED_LOG="$FOLDER/Removed.txt"  ## It's better to place this somewhere not in "$FOLDER" to not confuse timestamps everytime it is updated.

if [[ ! -d $FOLDER ]]; then
    echo "Directory does not exist: $FOLDER" >&2
elif read TIMESTAMP < <(exec find "$FOLDER" -type d -printf "%T@\n" | cut -f 1 -d . | sort -nr); [[ $TIMESTAMP != +([[:digit:]]) ]]; then
    echo "Unable to get timestamp of directory: $FOLDER" >&2
else
    STATE=$(exec find "$FOLDER" -mindepth 1 | sort)

    for (( ;; )); do
        sleep 5

        if [[ -d $FOLDER ]] && read NEWTIMESTAMP < <(exec find "$FOLDER" -type d -printf "%T@\n" | cut -f 1 -d . | sort -nr) && [[ NEWTIMESTAMP -gt TIMESTAMP ]]; then
            NEWSTATE=$(exec find "$FOLDER" -mindepth 1 | sort)

            ADDED=$(comm -2 -3 <(echo "$NEWSTATE") <(echo "$STATE"))
            [[ -z $ADDED ]] && ADDED='nothing'

            LOST=$(comm -2 -3 <(echo "$STATE") <(echo "$NEWSTATE"))
            LOST_ORIG=$LOST
            [[ -z $LOST ]] && LOST='nothing'

            alert --idea "$FOLDER:

$ADDED
*INSERTED*.

$LOST
*REMOVED*."

            [[ -n $LOST_ORIG ]] && echo "$LOST_ORIG" >> "$REMOVED_LOG"

            read TIMESTAMP < <(exec find "$FOLDER" -type d -printf "%T@\n" | cut -f 1 -d . | sort -nr) && [[ TIMESTAMP -ge NEWTIMESTAMP ]] || TIMESTAMP=$NEWTIMESTAMP
            STATE=$NEWSTATE
        fi
    done
fi

你想增加这一行：

prev=$(ls "$folder" | tr '\n' '\n'  > /tmp/prev.txt)

类似于：

prev=$(ls "$folder"/* | tr '\n' '\n'  > /tmp/prev.txt)
