The s6-chown program

s6-chown changes the owner and/or group of a file.

Interface

     s6-chown [ -U ] [ -u uid ] [ -g gid ] file

• s6-chown changes file's owner to (numeric) uid and group to (numeric) gid.
• If uid isn't provided, the owner remains the same; if gid isn't provided, the group remains the same.
• The -U option sets uid to the value of the UID environment variable and gid to the value of the GID environment variable. This makes s6-chown easily usable with s6-envuidgid: s6-envuidgid account s6-chown -U file changes file's uid and gid to account's.

Posixness

s6-chown is not suitable as a Single Unix chown program.
