fuidshift - Man Page

UID/GID shifter

This tool lets you remap a filesystem tree, switching it from one set of UID/GID ranges to another.

This is mostly useful when retrieving a wrongly shifted filesystem tree from a backup or broken system and having to remap everything either to the host UID/GID range (uid/gid 0 is root) or to an existing container's range.

A range is represented as <u|b|g>:<first_container_id>:<first_host_id>:<size>. Where "u" means shift uid, "g" means shift gid and "b" means shift uid and gid.
