Simple use and configuration of vim

Vim, Gedit is a common Linux editor, today we will talk about Vim.

Note: Vim is an upgraded version of VI that is not only compatible with all VI directives, but also has some new features in it. Therefore, some time vim, VI will be mixed, sometimes for the sake of simplicity also generally use VI.

Basically vim can be divided into three states, namely command mode, insert mode and bottom line mode.

1) The command-line mode controls the movement of the screen cursor, the deletion of characters, words or lines, the movement of a section and the insertion mode, or the in-line mode.

2) Insert mode only in the Insert mode, you can do text input, press "esc" to return to the command line mode.

3) The bottom line mode saves or exits vim, or you can set the editing environment, such as searching for strings, listing line numbers ... such as However, in general we use the VIM to simplify the two mode, that is, the bottom line mode is also counted in the command line mode.

Vim file name is used to edit a file or create a new file and edit it. such as: Vim Abytec new Abytec file and edit-

Just enter VIM when the default is the command mode, you can see the lower left corner shows the file name-

Press "I" to enter the insert mode, you can see the lower left corner of the display "--insert--"-

Now you can start editing, after editing, press "ESC" to exit the Insert mode, enter the command mode, the command can use a variety of commands to manipulate the text, please reply to "vim command".

You can see "--insert--" in the lower left corner, enter the English character colon ":" into the bottom row mode-

X for Save and exit; Q for exit; q! To force exit; W to write; Wq to write and exit;

LS View current directory-

You can see more Abytec files. Next talk about Vim configuration, general vim system configuration file for/etc/vim under the VIMRC, but generally do not need to change the system files, and in/home/abytec (that is, your user name) under the new. vimrc file. Note: There is a point in front-
