How to remove new line character at end of file.

I need to remove new line character from end of file.
Suppose here are content.


a|b|c|d|r
a|b|c|d|r
a|b|c|d|r
<new line>


that means file contains 4 lines but data is there in 3 lines.
so I want that only 3 lines should be there in file.

Please help

Tried and It didn't remove it.
Manually problem is removed by placing cursor at last line then press back button.

sed: illegal option -- i
without -i its not giving correct results.
If there are two lines at end then its removing one.
