VIM can be very complicated for new users but when You can basic commands it is very capable tool. There is much easier text editor called nano. Both text editors is very good.

Cut copy and paste

Copy Specified Contet

You have two options after selecting a text or content. You can copy or cut. If you want to copy the content you should use the yy . The y key stands for the yank in vi/vim and used to copy the selected context. You can use the following keys to copy. This operation is also called vim yanking or vim yank.

Command Description
yy Copy the current line
y$ Copy from the current location to the end of the current line
yiw Copy current word
yaw Copy current word with leading and trailing spaces

Cut Specified Content

The second operation is the cut operation which is different from the copy. The cut operation is called delete in vi/vim that executed with the dd keys. The cut operation first deletes selected content and then paste the deleted content to the specified position. You can use the following table in order to cut.

Command Description
dd Cut the current line
3dd Cut 3 lines starting from the current line
d$ Cut from current cursor position to the end of file
dw Cut current word

Paste visual

The copied or cut content can be pasted into the current cursor location by using the p key. The p key will paste the yanked lines into the current location which will complete the copy and paste or cut and paste operation. This is paste key is very similar to the GUI-based text editors or windows right-click paste from clipboard because the content will be pasted from the memory which acts like a clipboard. But keep in mind that this will not paste from the GUI desktop of the Linux operating system. You should use your terminal paste shortcut after changing the Vim/Vi into insert mode. The terminal paste keys are generally CTRL+SHIFT+v.

As a command line and command based text editor Vim or Vi do not provides the right click and paste function. All the paste operation will be done via commands and keys. But GVIM is an exception which is the graphical variant of the Vim and provides some GUI tools and mouse clicks to paste the copied or cut content.

Duplicate Current Line

If you need to duplicate the current line where the cursor is located with simple keystrokes use the following ESC+yy+p keys.

System clipboard

From the console, type:

vim --version | grep clipboard

If you see +clipboard or +xterm_clipboard, you are good to go. If it's -clipboard and -xterm_clipboard, you will need to look for a version of Vim that was compiled with clipboard support. On Debian and Ubuntu, to obtain clipboard support install the packages vim-gtk or vim-gnome.

Cut and copy

# Yank the selected text into the unnamed(default) register
# Yank into register a
# Yank into the system clipboard


# paste from the unnamed register
# paste from register a
# Paste from the system clipboard

Search and replace

For example, to search for the first occurrence of the string ‘foo’ in the current line and replace it with ‘bar’, you would use:


To replace all occurrences of the search pattern in the current line, add the g flag:


If you want to search and replace the pattern in the entire file, use the percentage character % as a range. This character indicates a range from the first to the last line of the file:


If the {string} part is omitted, it is considered as an empty string, and the matched pattern is deleted. The following command deletes all instances of the string ‘foo’ in the current line:


Instead of the slash character (/), you can use any other non-alphanumeric single-byte character except as a delimiter. This option is useful when you have the ‘/’ character in the search pattern or the replacement string.

For example, to substitute all occurrences of ‘foo’ to ‘bar’ in all lines starting from line 3 to line 10 you would use:


Undo Changes in Vim / Vi

Vim keeps track of all the changes you made in the current session. The undo command undoes one or more changes in the order in which they were made.

To undo changes in Vim and Vi use the u, :u or :undo commands:

If you are in insert or any other mode, press the Esc key to go back to the normal mode, which is also known as command mode.

Type u to undo the last change. In Vim, the u command also accepts quantifiers. For example, if you want to undo the four last changes, you would use 4u.

Make sure you’re typing lowercase u, not the uppercase U command, which undoes all latest changes on one line. If you accidentally type U you can undo the change with u

Redo Changes in Vim / Vi

The redo feature reverses the action of undo.

To redo a change in Vim and Vi use the Ctrl-R or :redo:

Press the Esc key to go back to the normal mode.

Use Ctrl-R (press and hold Ctrl and press r) to redo the last change. In Vim, you can also use quantifiers. For example, if you want to redo the 4 last changes, you would type 4Ctrl-R.

Each undo command can be reversed by a redo command.
