you can try this, in the parent directory of all these directories, type
find ./ -name "DATA_File_name" -exec sed "1,${N}d" {} > NEW_file_name \;should be enough, you will have both new and old files, after confirmation, you can move new ones to overwrite old ones.

Hi all,
I have about eighty directories, called data-nn, where nn=00,01,02,.... in each of these directories I have among others, an (ascii) data file with many thousends lines. This data file has the same name in all directories.
I would like to know if it is possible, via a bash script, to delete the first N lines in this data file in all directories. The modified file can overwrite the old one.
Many thanks in advance,
Fabio Zyserman
