如何在Linux中获得随机文件？ 包括子目录

Question

Lets say I am in /home/myuser

there are 90,000 files there inside 3000 directories.

How can I write a bash function or with linux commands to get one random file?

It could be C as well I suppose

Answer 1

You can list all your files and then pick a random line between them:

find /home/myuser | sort -R | head -n1

However this is not very efficient, and could take a while, but is easy to understand. You can work from here.

Answer 2

您可以将shuf用于此任务，例如set globstar选项并尝试

shuf -e path/**/*.txt | head -n1
