Multiple sed -e command usage in linux

Question

I am trying to understand the below command. Looked many tutorials and references. Can anyone help What actually it does.

 sed -e '$d' -e '1,1d' File1 >File2

Answer 1

$d wil delete the last line

To delete lines between n and m use n,md. ie. 1,1d is same as 1d, which deletes the first line

So sed -e '$d' -e '1,1d' File1 >File2 will remove first and last line from File1 and send to file2
