Command to remove First and Last line from a File

I have a file from which the Header and the Trailer lines need to be removed. They are confirmed to be the first and the last lines in the file.

I have tried a few commands, but not successful yet. It needs to be implemented urgently, hence any help is greatly appreciated.

Just found out from another post in this forum, that the following command works perfectly:

sed -e '2,$!d' -e '$d' file

replace 'file' with your filename.
