The thing I don't like is your script has the potential of
modifying unintended files. I'd use one of the shell's
variable expansion features to strip just what was unwanted.
for f in *.dat
do
echo mv $f ${f/zt...aa/aa}
done
Fill in the ... with the actual chars.
The "echo" gives a test run to see what will be done with no echo.
mv may complain about ",dat" files that don't match the "zt...aa"
pattern, "original and new name identical.
