ls -rtl *.dat | grep Jan | awk '{print $9}' | rm *.dat
This is basically equivalent to

Code:
ls -rtl *.dat | grep Jan | awk '{print $9}' >/dev/null
rm *.dat

so no wonder your *.dat files are gone. The right syntax for using the pipeline (and avoiding the Useless Use of grep | awk) is

Code:
ls -rtl *.dat | awk '/Jan/{print $9}' | xargs rm

or you could use backticks, but they are always a bit perilous, IMHO.
