Hi,
Would like to remove first line and last non-empty line from a file.

Since I'm expecting very large files, could you suggest me an efficient way of performing this please. It would be good if we can achieve in one liner script.
I saw few examples but they redirect the file to another new file after removing.

please help

# cat input.txt
header_row
one
two
three
four
five
footer_row
<blankline>
<blankline>

# after removing
# cat input.txt
one
two
three
four
five
