How about:
--- 8< cut here ---
#!/bin/bash
pushd /cygdrive/d/pc1
for file in *.csv; do
if [ "${file##new_}" != "${file}" ]; then next; fi
cat "${file}" | uniq > "new_${file}"
done
popd
-------------------
I Guess bas is like perl: TIMTOWTDI ;)

Apart from that, you will overwrite the new file each time ;-)
$ for i in /cygdrive/d/pc1/*.csv; do cat $i | uniq >
/cygdrive/d/pc1/$1.new; done
Now you avoid that your new files are picked also and all new files have
new names (a .new appended).
Other approaches to do something like that:
find /cygdrive/d/pc1/*.csv -exec uniq \{} \{}.new \;
refer the manuals ...
