Android's toybox

More capable than you expected

Android ships a stripped down version of standard Linux commands and tools via toybox. toybox is comparable to busybox, it consists of a single executable in /vendor/bin/toybox which provides all the functionality.

For example, to view extended file attributes - xattrs:

kagura:/persist # toybox getfattr -d /persist/
# file: .
security.restorecon_last="�+4����	\�	�X�7tu�"
security.selinux="u:object_r:persist_file:s0"

To wipe a particular xattr to force restorecon_recursive to run on next boot:

kagura:/persist # toybox setfattr -x security.restorecon_last /persist/
kagura:/persist # toybox getfattr -d /persist/
# file: .
security.selinux="u:object_r:persist_file:s0"
