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
** āāāāā- OR āāāāā-**
tail -n +2 $file >> headerless.txt
Personally I think the tail option is cosmetically more pleasing and more readable but probably because Iām sed-challenged.
Which method is fastest?
