<pre><code>find /path/to/ -type f -print0 | xargs -0 file | grep -i image
</code></pre>

This uses the <code>file</code> command to try to recognize the type of file, regardless of filename (or extension).

If <code>/path/to</code> or a filename contains the string <code>image</code>, then the above may return bogus hits. In that case, I'd suggest

<pre><code>cd /path/to
find . -type f -print0 | xargs -0 file --mime-type | grep -i image/

blocks|key|1279636|text|在对@Dennis+Williamson上面的响应的补充中，如果您希望相同的正则表达式对文件扩展名不区分大小写，请使用-iregex：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1279637|find+/path/to+-iregex+".*\.$jpg\%7Cgif\%7Cpng\%7Cjpeg$"+>+log|code-block|syntax|javascript|1279638|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

In supplement to @Dennis Williamson 's response above, if you want the same regex to be case-insensitive to the file extensions, use -iregex :

in case files have no extension we can look for file mime type

<pre><code>find . -type f -exec file -i {} + | awk -F': +' '{ if ($2 ~ /audio|video|matroska|mpeg/) print $1 }'
</code></pre>

where (audio|video|matroska|mpeg) are mime types regex 

&amp;if you want to delete them:

<pre><code>find . -type f -exec file -i {} + | awk -F': +' '{ if ($2 ~ /audio|video|matroska|mpeg/) print $1 }' | while read f ; do
 rm "$f"
done
</code></pre>

or delete everything else but those extensions:

<pre><code>find . -type f -exec file -i {} + | awk -F': +' '{ if ($2 !~ /audio|video|matroska|mpeg/) print $1 }' | while read f ; do
 rm "$f"
done
</code></pre>

notice the !~ instead of ~

I need to find all image files from directory (gif, png, jpg, jpeg).

<pre><code>find /path/to/ -name "*.jpg" &gt; log
</code></pre>

How to modify this string to find not only .jpg files?

How to use find command to find all files with extensions from list?

我需要找到目录中的所有图像文件(gif，png，jpg，jpeg)。find /path/to/ -name "*.jpg" > log如何修改此字符串，使其不仅能找到.jpg文件？
