linkdata2sd  linkdata2sd


is a script designed to run inside Android phones to migrate data/cache directories from internal storage to sd card.

Assuming you have Link2sd installed in your phone, this script covers the data handled by premium licence only.

You are required to have partitioned the sd-card and have /data/sdext2 mounted. If you don't know how to do this you should start by booting TempCWM to partition the sd (backup first!), and let Link2sd detect the new partition.

This is not an app, it's a sh script. It was tested on Android 2.3. Aside from that there are no dependencies. I don't know if it works on newer devices.

To run it you could install a terminal emulator app or login into the device via a ssh server app.

Once in terminal

$su      (enter root mode, if not already)
#sh    (wherever the script is located)

In default mode the app prompts the installed apps' data/cache sorted by size (in decreasing order). From here on you can:

  • move the data to/from the sd card (link/unlink)
  • launch a shell inside the data directory (sh)
  • make a snapshot of current data (snap)
  • reuse a previous snapshot
  • delete the data (delete)

Sample session

This sample shows aquamail and whatsapp apps data linked in sdcard preceded by the listing of all the snapshots taken. In the aquamail case, the linked snapshot is 20160319_041426.
