Linux的文件夹删除超过1年，超过3个文件 [英] Linux removing folders older than 1 year and more than 3 files

问题描述

我在写一个Ant脚本来清理存档文件夹

I'm writing an ant script to clean up an archive folder

下面就是我需要把它清理干净：我需要删除超过一定数额的天老的文件夹，并在其中有超过3个文件。因此，举例来说，如果一个文件夹为300天之久，但只有3个文件比它不会被删除。

Here's how I need to clean it up: I need to delete folders old than a certain amount of days AND has more than 3 files in it. So for example if a folder is 300 days old but only has 3 files than it will NOT be deleted.

我知道我可以ssh到归档，并做找到-mtime + 365 -exec室射频{}; \\ 删除文件超过1年，但我不知道如何计算最低的3个文件

I know I can ssh into the archive and do find -mtime +365 -exec rm -rf {} ;\ to delete files older than 1 year but I don't know how to account for the minimum of 3 files

我也知道，找到型的F |厕所-l 将列出的文件数，但并没有真正的脚本方面的帮助。

I also know that find -type f | wc -l will list the number of files, but that doesn't really help in terms of scripting

任何想法？

推荐答案

选择可以自定义文件集删除。

ANT selectors enable you to customize the fileset to delete.

请尝试以下操作：

<target name="purge">

    <tstamp>
        <format property="touch.time" pattern="MM/dd/yyyy hh:mm aa" offset="-300" unit="day"/>
    </tstamp>

    <delete>
        <fileset dir="${src.dir}">
            <date datetime="${touch.time}" when="before"/>

            <scriptselector language="javascript"><![CDATA[
                if (file.getParentFile().list().length > 3) {
                    self.setSelected(true);
                }
                else {
                    self.setSelected(false);
                }
            ]]> </scriptselector>
        </fileset>
    </delete>
</target>
