Question

cp is the shell command for that copies files. part of the synopsis section of the manpage for cp is below.
cp -pfip source file target file
based on this synopsis, which of the following is not true?
the following command is valid:
$ cp part1.cpp
the following command is valid:
$ cp main.cpp backup.cpp
target file is a fill-in-the-blank

Explanation:

1. The synopsis cp [-Pfip] source_file target_file shows cp requires a source and target file (or target directory) for basic usage.
2. The command $ cp part1.cpp only provides a source file, no target, so it is invalid.
3. The command $ cp main.cpp backup.cpp provides both a source and target file, matching the synopsis, so it is valid.
4. In manpage synopses, underlined text like target_file is a placeholder (fill-in-the-blank) for the user's actual target file name.
5. The question asks which statement is not true, so the claim that $ cp part1.cpp is valid is the false statement.

Answer:

The following command is valid:
$ cp part1.cpp
