Copying files in ADB shell with run-as

Question

Is there a way to write a script that will copy files from an ADB shell using run-as?

The only way I know of to copy in the adb shell is using cat source >

Answer 1

you could just change the permission of the directory and then pull all the files out. but for me i was looking for just one shared preference file and i was able to get the data like this:

PACKAGE='com.mypackage.cool'
SHAREDPREF_FILE="${PACKAGE}_preferences.xml"

    adb shell "run-as $PACKAGE cat /data/data/$PACKAGE/shared_prefs/$SHAREDPREF_FILE">$SHAREDPREF_FILE

now we have the data of the sharedpreference file stored in a file of the same name.
