In the vi editor, which of the following commands will copy the current line into the vi buffer?
In the vi editor, the command 'yy' is used to copy (yank) the current line into the vi buffer. Once the line is copied, it can be pasted using the 'p' command. The other options do not achieve this: 'c' changes the current line, 'cc' deletes the current line and enters insert mode, '1c' changes the specified line number, and '1y' yanks the specified line number, not the current line.
The correct option is: D. yy In the vi editor, the command `yy` is used to copy the current line into the vi buffer. Here's an explanation of each option: A. `c`: This command is used to change (delete and enter insert mode) the current line, not to copy it. B. `cc`: This command is used to delete the current line and enter insert mode, not to copy it. C. `1c`: This command is used to change (delete and enter insert mode) the specified line number, in this case, line 1, not to copy the current line. D. `yy`: This command yanks (copies) the current line into the vi buffer. The line can then be pasted (put) using the `p` command. E. `1y`: This command yanks (copies) the specified line number, in this case, line 1, into the vi buffer, not the current line. Therefore, option D, `yy`, is the correct command to copy the current line into the vi buffer.
