I haven't been able to try this one but,

00 02 * * * /usr/bin/find / -type f -name "core" -exec file > /home/root/core_report {} \;

should probably be close to what you're looking for.

1) write a script :
e.g. name=/usr/local/bin/chk
#!/bin/sh

what $1 >/tmp/$1.what
file $1 >/tmp/$1.file

2) run the command
find / -name core -exec /usr/local/bin/chk {} \;

Sorry, I should have mentioned that that was intended to be a crontab entry running at 2:00 AM everyday.

find . -name core -exec file {} \; -exec what {} \; >> outputfile

If you only want to search in /, and not in other fielsystems, add a '-xdev' to your find statement.

find / -xdev -name core -type -exec file {} >> yourlogfile \;

This will only search the root filesystem, find regular (normal) files, and executes the 'file' command, and APPEND the output to yourlogfile.

Since you may want to execute several commands on 1 core-file, I think you should follow Jean-Luc's solution by writing a separate script to do this.

I would prefer something like:
#!/bin/sh

(
echo $1
what $1
file $1
) >> /root/yourlogfile

Or even put the date in the logfilename.
(something like: yourlogfile=/root/logfile`date "+...."`
and change the last line to:
) >> $yourlogfile
