Good afternoon, I have executed the following command by mistake:

sudo chown -R www-data:www-data /var/cache

I want to undo this, so I am asking if anyone may know what is the default owner of /var/cache subdirectories?

Is it root? Should I execute: sudo chown -R root:root /var/cache

Thank you in advance for your sharings.

For most sub-directories under /var/cache, the owner and group are both "root", but with a few exceptions. For example, the owner and group of "man" directory are "man". Normally you can try to re-set them to both "root".

/var/cache is owned by root:root and, in theory (not that I have ever tried), you can remove anything inside /var/cache because it is, well, cache data.

In my case:

root@xxx:~# ls -l /var/cache
