'Android Shell root rm folder failed
I created a folder hdr in /sdcard/DCIM/Camera/ by linux c function: mkdir(), but when I set permission, I used '777' but not '0777' uncarefully, and the folder permission like this:
xxx:/sdcard/DCIM/Camera # ll
total 6
drwxrws--T 5 u0_a217 media_rw 3452 2022-03-01 09:26 hdrd
...
xxx:/sdcard/DCIM/Camera/hdrd # ll
total 9
drwxrws--T 2 u0_a217 media_rw 3452 2022-02-25 10:13 20220225_101334_1645755214821
...
xxx:/sdcard/DCIM/Camera/hdrd/20220225_101334_1645755214821 # ll
total 1952
-rw-rw---- 1 u0_a217 media_rw 460800 2022-02-25 10:13 IMG_20220225_101334_1645755214821_0_640x480_p_640x480_SRC.NV12
then , I wanna delete this hdrd folder so I used rm -r hdrd, there is an error:
xxx:/sdcard/DCIM/Camera # rm -r hdrd/
rm: IMG_20220225_101334_1645755214821_0_640x480_p_640x480_SRC.NV12: Math result not representable
...
I don't know why delete failed, I was in root state.
PS: I use lsattr fuction, but not succeed:
xxx:/sdcard/DCIM/Camera # lsattr hdrd
lsattr: reading flags 'hdrd/20220225_101334_1645755214821': Function not implemented
