Display find results, and pipe to xargs

I have an overnight script which runs across a large directory to repair permissions and ownership. I also have this command output the list of files affected so that cron can email these as a log file. Previously I had the command in the form:

Code:

find /path/to/files -not -user myname -print -exec chown myname "{}" \;

As it is a long command sometimes I never receive a log email even though the ownership and permissions have changed, so I want to make the script more efficient. As such I have changed the command to:

Code:

find /path/to/files -not -user myname -print0 | xargs -0 chown myname

Is there anything I can do to that command so that it sill lists the files on standard output so that they will be emailed by cron in addition to piping them to xargs?

I cannot include the -print action in the find command as this will also be piped to xargs. Likewise if I include an -exec action with an echo command. Also I do not want to use the -t option with xargs as I just want the list of files and not the chown commands it generates.

The best solution I have been able to come up with is to use tee to ssave output in a temporary file to display afterwards, but I am hoping there is better solution.

Thanks,

Michael.

I have been using unix on and off for a number of years. I am not a sys admin. I use what I need. I have googled this, but I really can't figure out what is the difference between using xarg and just using a regular pipe? Why do I need to include xarg sometimes and how do I know when I need it?

chown

chown(1B)					     SunOS/BSD Compatibility Package Commands						 chown(1B)

NAME

       chown - change owner

SYNOPSIS

       /usr/ucb/chown [-fR] owner[.group] filename...

DESCRIPTION

       chown  changes  the  owner of the filenames to owner. The owner can be either a decimal user ID (UID) or a login name found in the password
       file. An optional group can also be specified.  The group can be either a decimal group ID (GID) or a group name found in the GID file.

       In the default case, only the super-user of the machine where  the file is physically located can change the owner. The	system	configura-
       tion  option {_POSIX_CHOWN_RESTRICTED} and the privileges PRIV_FILE_CHOWN and PRIV_FILE_CHOWN_SELF also affect who can change the ownership
       of a file. See chown(2) and privileges(5).

OPTIONS

       The following options are supported:

       -f	Do not report errors.

       -R	Recursively descend into directories setting the ownership of all files in each directory encountered.	When  symbolic	links  are
		encountered, their ownership is changed, but they are not traversed.

USAGE

       See largefile(5) for the description of the behavior of chown when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).

FILES

       /etc/passwd	       Password file

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
