chown on a sdcard directory impossible... (programming.dev)

submitted 1 month ago by [email protected] to c/[email protected]

12 comments fedilink hide all child comments

Hi,

I would like to change the owner of a directory on the sdcard /sdcard/aDirectory

I have a terminal installed on my Android 10 (LineageOS 17) com.android.terminal

sudo is not present so I use su and it works.

su
#Terminal was granted Superuser rights

cd /sdcard
chown 10:10 aDirectory
#I don't get any error message.

stat aDirectory
#Uid (0/root)

So the owner stay root no matter what I'm doing, any ideas ?

Unless the SD card is using a Linux filesystem, you won't be able to use Linux access permissions.

Most SD cards are preformatted to FAT or exFAT in order to maximise compatibility. If you don't need to use the card on any non-linux devices you should be able to reformat it and gain the ability to chown/chmod (should go without saying, but back up any data on the card you want to keep before this)

There are other comments here which might have some relevance but imo this one is the most likely the most applicable. I've had this experience with other filesystems over and over and it seems like it's almost always a problem. Apparently NTFS supports permissions in a similar way to Linux if you set it up exactly right, but I've never taken the time to try that.
