How can I delete the first (!) line of a text file if it\'s empty, using e.g. sed or other standard UNIX tools. I tried this command:

sed \'/^$/d\' < somefile

    Delete the first line of all files under the actual directory if the first line is empty :
    find -type f | xargs sed -i -e '2,$b' -e '/^$/d'
