Post [Q] Script Copy from sdcard to internal via script manager

My phone is rooted. Script manager has su and I clicked the green skull

I can copy via terminal as well as file manager apps.

Can someone give me any help?

Every time I try something it does not work or give errors.

One example I am trying is this:

umount /data/data/app_dir/prefs/ mount -o bind /sdcard/data/wow/shared_prefs/ /data/data/jp.gree.modernwar/prefs/

I tried other copy commands but I get segmentation error etc

Feel like I am running in circles.

is there not a simple copy this folder sdcard/whatever to /data/data/app_dir

thank you
