Copy, cut and paste in Linux

Here is how to cut-and-paste or copy-and-paste text using a visual selection in Vim.

Cut and paste:

1. Position the cursor where you want to begin cutting.
2. Press v to select characters (or uppercase V to select whole lines).
3. Move the cursor to the end of what you want to cut.
4. Press d to cut (or y to copy).
5. Move to where you would like to paste.
6. Press P to paste before the cursor, or p to paste after.

Copy and paste is performed with the same steps except for step 4 where you would press y instead of d:

• d = delete = cut
• y = yank = copy

Multiple copying

Deleted or copied text is placed in the unnamed register. If wanted, a register can be specified so the text is also copied to the named register. A register is a location in Vim's memory identified with a single letter. A double quote character is used to specify that the next letter typed is the name of a register.
For example, you could select the text hello then type "ay to copy "hello" to the a register. Then you could select the text world and type "by to copy "world" to the b register. After moving the cursor to another location, the text could be pasted: type "ap to paste "hello" or "bp to paste "world". These commands paste the text after the cursor. Alternatively, type "aP or "bP to paste before the cursor.

Windows clipboardWhen using Vim under Windows, the clipboard can be accessed with the following:

• In step 4, press Shift+Delete to cut or Ctrl+Insert to copy.
• In step 6, press Shift+Insert to paste.

Different instances

How to copy and paste between two instances of Vim on different Linux consoles?
After copying text, open a new buffer for a new file:

:e ~/dummy

• Paste the text to the new buffer.
• Write the new buffer (:w).
• Switch to the previous buffer (:bp) to release *.swp.
• Now switch to the other console.
• Put the cursor at the desired place.
• Read the dummy file (:r ~/dummy)

Increasing the buffer size

By default, only the first 50 lines in a register are saved, and a register is not saved if it contains more than 10 kilobytes. :help 'viminfo'
In the example below, the first line displays the current settings, while the second line sets:

• '100 Marks will be remembered for the last 100 edited files.
• <100 code=""> Limits the number of lines saved for each register to 100 lines; if a register contains more than 100 lines, only the first 100 lines are saved.
• s20 Limits the maximum size of each item to 20 kilobytes; if a register contains more than 20 kilobytes, the register is not saved.
• h Disables search highlighting when Vim starts.

:set viminfo?
:set viminfo='100,<100 h="" pre="" s20="">
