What errors do you get? You're applying the logics designed for "FILE" and depending on its structure and wellbehavedness to a totally different data set. That can't fly. Try instead

chown
CHOWN(1) FSF CHOWN(1)NAME
chown - change file owner and group
SYNOPSIS
chown [OPTION]... OWNER[:[GROUP]] FILE...
chown [OPTION]... :GROUP FILE...
chown [OPTION]... --reference=RFILE FILE...
DESCRIPTION
This manual page documents the GNU version of chown. chown changes the user and/or group ownership of each given file, according to its
first non-option argument, which is interpreted as follows. If only a user name (or numeric user ID) is given, that user is made the owner
of each given file, and the files' group is not changed. If the user name is followed by a colon or dot and a group name (or numeric group
ID), with no spaces between them, the group ownership of the files is changed as well. If a colon or dot but no group name follows the
user name, that user is made the owner of the files and the group of the files is changed to that user's login group. If the colon or dot
and group are given, but the user name is omitted, only the group of the files is changed; in this case, chown performs the same function
as chgrp.
OPTIONS
Change the owner and/or group of each FILE to OWNER and/or GROUP.
-c, --changes
like verbose but report only when a change is made
--dereference
affect the referent of each symbolic link, rather than the symbolic link itself
-h, --no-dereference
affect symbolic links instead of any referenced file (available only on systems that can change the ownership of a symlink)
--from=CURRENT_OWNER:CURRENT_GROUP
change the owner and/or group of each file only if its current owner and/or group match those specified here. Either may be omit-
ted, in which case a match is not required for the omitted attribute.
-f, --silent, --quiet
suppress most error messages
--reference=RFILE
use RFILE's owner and group rather than the specified OWNER:GROUP values
-R, --recursive
operate on files and directories recursively
-v, --verbose
output a diagnostic for every file processed
--help display this help and exit
--version
output version information and exit
Owner is unchanged if missing. Group is unchanged if missing, but changed to login group if implied by a `:'. OWNER and GROUP may be
numeric as well as symbolic.
