Generally speaking, centos or other Linux operating systems we use already have vim installed by default. You can check directly to see if it is installed. [root@zmgaosh ~] # rpm-qf which vimvim-enhanced-7.4.629-6.el7.x86_64vim editor has three working modes: command mode, input mode, and last line mode

Remember a few points:

Enter the file for the first time in command mode "insert" is in edit mode input: (lower left corner) is command line mode

Let's first look at the input mode:

Input mode

Method to enter edit mode: an i o An I O (any letter can be switched to edit mode)

Here's an explanation: (see table)

1) insertion mode

Note: press these letters not to enter a character, but to switch to insert mode. Press ESC to return to command mode, and sometimes you need to press esc twice to ensure that you can do so

What command line mode can do in command line mode: 1. Cursor positioning class:

H: left

J: lower

K: above

L: right

The number 0 and the home key indicate switching to the beginning of the line

The $and end keys indicate switching to the end of the line

Gg means to quickly navigate to the first line of a document

G: navigate to the last line

3gg or 3G means to quickly navigate to line 3

two。 Regular matching class:

/ ^ d looks for content that starts with what, here is to find content that starts with d

/ t $find content that ends in t

Tip: if you want to open the file and the cursor directly to the last line of the file, you can use + such as we want to open / etc/passwd, open and let the cursor on the last line vim + / etc/passwd3. Text editing class: copy, paste, delete, undo

4. Visual class operation

V: enter visualization mode

R: erase, rewrite, enter replacement mode

For example:

Add # CTRL+V to multiple lines-select the line to add #-enter uppercase I-add # to the first line-double-click esc

Last line mode operation:

1. Save exit command

two。 Invoke external commands

:! + command

For example, to view the current ip

R read the file and append it to the document

3. Text replacement (difficulty is also key)

Format: range (% all content) s delimiters old content delimiters new content (delimiters can be customized)

For example:

1 s/bin/gaosh 3 replace the first bin that appears in lines 1 to 3 to replace with gaosh:1,3 s/bin/gaosh/g replace all the bin found in lines 1 to 3 and replace it with gaosh:3 s/bin/aaaaa # only replace the contents in line 3

:% s/do/gaosh/g replaces all do in the text with gaosh:% s/do/gaosh/gi replaces all do in the text with gaosh and ignores the case of do:% s@a@b@g replaces all an in the text with b4. Customize the vim usage environment
