What is the GID/UID of the system on Android?

How do I identify the number (integer value) of a particular group associated with a file?

ls -l
drwxr-x--x root     system              2014-11-26 10:59 xyz

I have managed to check that group id of root is 0. What is the corresponding number of group id for system?

I need to change the group of my file to system. How do I do it using chown? gid_t is internally of int type. So what value should I pass to make it system? How do I know?

Solution

  • Check with AID_XXX Ex: AID_SYSTEM in the source code. The corresponding value is the integer value of it.

    AID_SYSTEM is 1000

    Similarly it can be found for other groups as well.

    I don't know if there is a better way.
