Mar 16 10:00 AAA20070316.TXT.070316.01.01.02

I'm now using
find . -name AAA* -exec mv {} AAA.TXT \;

but since there are 2 files exist, this command will fail.


That command fails because you didn't quote the wildcard. If you quote the wildcard, it will move all the AAA* files leaving only the most recent.

The aim is the ftp the latest file back and bcp to the database.

Code:
set -f
set -- AAA*
shift $(( $# - 1 ))
mv "$1" AAA.txt

That assumes that the files sort themselves from oldest to newest (as in the examples you gave). If that is not the case, and the files are sanely named (again, as in the examples you gave):
Code:
set -f
set -- $( ls -t AAA* )
mv "$1" AAA.txt

DH_INSTALLDEB(1)						     Debhelper							  DH_INSTALLDEB(1)

NAME
dh_installdeb - install files into the DEBIAN directory SYNOPSIS
dh_installdeb [debhelperoptions] DESCRIPTION
dh_installdeb is a debhelper program that is responsible for installing files into the DEBIAN directories in package build directories with the correct permissions. FILES
package.postinst package.preinst package.postrm package.prerm These maintainer scripts are installed into the DEBIAN directory. Inside the scripts, the token #DEBHELPER# is replaced with shell script snippets generated by other debhelper commands. package.triggers package.shlibs These control files are installed into the DEBIAN directory. package.conffiles This control file will be installed into the DEBIAN directory. In v3 compatibility mode and higher, all files in the etc/ directory in a package will automatically be flagged as conffiles by this program, so there is no need to list them manually here. package.maintscript Lines in this file correspond to dpkg-maintscript-helper(1) commands and parameters. Any shell metacharacters will be escaped, so arbitrary shell code cannot be inserted here. For example, a line such as "mv_conffile /etc/oldconffile /etc/newconffile" will insert maintainer script snippets into all maintainer scripts sufficient to move that conffile. A versioned Pre-Dependency on dpkg is needed to use dpkg-maintscript-helper(1). An appropriate Pre-Dependency is set in ${misc:Pre-Depends} ; you should make sure to put that token into an appropriate place in your debian/control file. SEE ALSO
debhelper(7) This program is a part of debhelper. AUTHOR
