as simple as:

<pre><code>find . -mtime -1 | xargs tar --no-recursion -czf myfile.tgz
</code></pre>

where <code>find . -mtime -1</code> will select all the files in (recursively) current directory modified day before. you can use fractions, for example:

<pre><code>find . -mtime -1.5 | xargs tar --no-recursion -czf myfile.tgz
</code></pre>

blocks|key|1561695|text|您可以直接使用tar来完成此操作，甚至更好：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1561696|tar+-N+'2014-02-01+18:00:00'+-jcvf+archive.tar.bz2+files|code-block|syntax|javascript|1561697|这指示tar压缩比2014年1月1日18:00:00更新的文件。|1561698|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

You can do this directly with tar and even better:

<pre><code>tar -N '2014-02-01 18:00:00' -jcvf archive.tar.bz2 files
</code></pre>

This instructs tar to compress files newer than 1st of January 2014, 18:00:00.

This will work for some number of files. You want to include "-print0" and "xargs -0" in case any of the paths have spaces in them. This example looks for files modified in the last 7 days. To find those modified before the last 7 days, use "+7". 

<pre><code>find . -mtime -7 -print0 | xargs -0 tar -cjf /foo/archive.tar.bz2
</code></pre>

As <a href="http://content.hccfl.edu/pollock/Unix/FindCmd.htm" rel="noreferrer">this page</a> warns, xargs can cause the tar command to be executed multiple times if there are a lot of arguments, and the "-c" flag could cause problems. In that case, you would want this:

<pre><code>find . -mtime -7 -print0 | xargs -0 tar -rf /foo/archive.tar
</code></pre>

You can't update a zipped tar archive with tar, so you would have to bzip2 or gzip it in a second step.

You can get a list of files last modified later than x days ago with:

<pre><code>find . -mtime -x

Then you just have to tar and zip files in the resulting list, e.g.:

<pre><code>tar czvf mytarfile.tgz `find . -mtime -30`
</code></pre>

for all files modified during last month.

</code></pre>

For example you want files having modification date before the given date only, you may change <code>120</code> to <code>0</code> in <code>$DIFF_IN_DATE</code> parameter discarding the conditions of <code>$DIFF_IN_DATE1</code> parameter.

Similarly if you want files having modification date 1 hour before and after given date,
just replace <code>120</code> by <code>3600</code> in <code>if CONDITION</code>.

I'd rather not do this in PHP so I'm hoping a someone decent at shell scripting can help.

I need a script that runs through directory recursively and finds all files with last modified date is greater than some date. Then, it will tar and zip the file(s) keeping the path information.

Shell Script — Get all files modified after <date>

我不想用PHP来做这件事，所以我希望一个擅长shell脚本的人能帮上忙。我需要一个脚本，通过目录递归运行，并找到所有文件的最后修改日期是大于一些日期。然后，它将压缩并压缩保存路径信息的文件。
