You told us you want everything except for the last and the first line, but presented us a 5-line file in your first post. Does this mean you want to skip all empty lines?
Supposing you want empty lines to go into your result (this would yield not only the line "my name is mani" in you first example, but also the two empty lines surrounding it) you could use:
# cat <file> | sed -n '1d; $d; p'
This will ignore the last and first line and print out everything else. In case you want to skip empty lines (lines containing only whitespace) too:
# cat <file> | sed -n '1d; $d; /^[<blank><tab>]*$/d; p'
To display the first/last line is trivial and could be done by sed too, but you have gotten a working solution already. To display the first nonblank line use:
# cat <file> | sed -n '/^[<blank><tab>]*$/d; /^..*$/ {; p; q;}'
You should be able to work out the solution for the last nonblank line now for yourself. "<blank>" and "<tab>" in the text above is to be replaced by literal blanks and tabs of course.
