How to remove a line from a file?

Question

Programming

Hello. Please help me solve the problem:
I need to delete a line from a text file. When deleting, the bottom lines move up (something that can be easily organized in notepad by hand).
The file is very large, so reading it to RAM or copying it to another is not suitable.

Answer 1

Alas, deleting a line from a text file is possible only in such a terrible way, because all subsequent bytes must be shifted by the length of the line.
