Remove the first two records from a bunch of files

Hi, i have lots of single-column text files in a directory and i want to remove from each of them the first two lines and print the result in multiple new single-column files.

i know that for one file the below tail command would just do the job :
Code:
tail -n +3 filename > new_filename

is there a way of applying this to all the files in my directory?

thanks in advance

One way:
Code:
awk 'FNR>2{print > "new_" FILENAME}' *

Another way:
Code:
find <Path> -name "<FileName>" -type f | \
while read fname
do
tail -n +3 "${fname}" > "${fname}.new"
done

Note, it will also find subdirectories! If not needed, use:
Code:
find <Path> -maxdepth 1 -name "<FileName>" -type f

Code:
$ for i in $(find full_path -type f -print); do sed '1,2d' $i > ${i}_new ; done
