 ## Unreleased
 
+- New `fix-perms` command: `sudo terractl fix-perms <name>` gives every file of an instance back to the `terraria` user and reapplies the usual modes (group can read, others nothing; server binaries executable), e.g. after copying worlds in as root. Symlinks are not followed. Works with `--host` too.
 - `list` warns about zips in `dist/` that the `terraria` user can't read (e.g. copied in with `scp -p` from a private file), and `info` lists them as `unreadable_zip=`. A server that fails to install because of one now says how to fix it (`sudo chmod 644 <zip>`) instead of just "cannot read", and a missing zip is reported as not found.
