In this answer (How can I remove the first line of a file with sed?) there are two ways to delete the first record in a file:

sed '1d' $file >> headerless.txt

** ā€”ā€”ā€”ā€”ā€”- OR ā€”ā€”ā€”ā€”ā€”-**

tail -n +2 $file >> headerless.txt

Personally I think the tail option is cosmetically more pleasing and more readable but probably because Iā€™m sed-challenged.

Which method is fastest?
