Linux nano editor commands common methods work notes

In this article, you may also sort out the commonly used nano command usage methods. If your memory is poor, use the text to record them and try again later.

1. Install the nano editor

1. CentOS

Yum-y install nano
2. Debian

Apt-get install-y nano
Some default Linux system environments do not have the nano editor installed. When executing the command, you will see "-bash: nano: command not found ", then we use the above command to install the nano editing environment.

II. Common usage of nano

1. Ctrl + X

Exit the current editor, and then prompt whether to save and exit. If you need to save, enter Y and press Enter. If you do not need to save, enter N and press enter.

2. Ctrl + O

Save the changes to the file.

3. Page flip

Ctrl + Y to the previous page, Ctrl + V to the next page

4. Search

Press Ctrl + W and enter the required keyword and press Enter. The first matching text will be located. If we need to see the following, Alt + W will be used to locate the next matching text.

5. Copy, cut, and paste

Copy the entire row: Alt + 6; cut and paste the whole row: Ctrl + K; paste: Ctrl + U

6. Fast moving

Ctrl + A move to the beginning of the row; Ctrl + E at the end of the row

Get help
After entering the nano interface, there are two menus below, for example, "^ G Get Help ". Its significance is as follows:

^ G means that the shortcut key is Ctrl + G, and "Get Help" is of course a function.

Follow these prompts to start using nano immediately, or press Ctrl + G to see help.

Note: In nano, black and white characters indicate shortcut key operations. "^" Indicates the Ctrl key, and Ctrl + G indicates the "^ G ". M represents the Alt key, and Alt + W represents the M-W ".

To sum up, for common users, we only need to learn simple editing, saving, and exiting. vi and nano functions are similar, so we don't need to compare them with others. We can use them.
