Permission denied when trying to write or create file on USB Drive #1855

Closed stevenleeS0ht closed 3 years ago

stevenleeS0ht commented 3 years ago

Problem description

All of the shell command or executable file in Termux are not able to write data or create file at place on USB flash drive, through I have permitted Termux to access data at storage.

Steps to reproduce

My USB drive have file system exFAT, it can be discovered and read/writed by File Manager.

Expected behavior

It should be able to write or create file on any User accessible directory and filesystem.

Additional information

Termux application version: 0.103
Android OS version: 10

stevenleeS0ht commented 3 years ago

One possibly reason might because is exFAT filesystem doesn't support file owner and permission, Termux just regard files permission as root.

However, in desktop linux, the situation is a little bit different, if the filesystem doesn't support permission, it will be open to everyone.

@fornwall and @xeffyr please have a look.

It is not possible without root currently, see duplicate issue https://github.com/termux/termux-app/issues/71.

Termux is only allowed to write to /sdcard and the folder Android/data/com.termux/files on the external sdcard, other places, including usb devices, are not possible to write to without root
