It was yesterday. The Nano was a suggested compiler and then found a good blog to learn. By the way.

Nano Command Guide

Today in the loss command, inadvertently entered the Nano, not too familiar with the command, the results do not know how to exit, save, quickly check the information, the original is such AH.

Code Listing 1.1: Opening or creating a new file

#Nano file name

The Nano is a single-mode editor that allows you to enter text directly. If you want to edit a configuration file like/etc/fstab, use the- w parameter, for example:

Code Listing 1.2: Disabling line Wrapping

#Nano-w/etc/fstab

Warning: This is very important. If you forget the-w parameter when you edit the configuration file , it may cause your system to fail to start or produce other exceptions.

Save and exit

If you want to save your changes, press Ctrl+o. To exit, press CTRL +X. If you do not save your changes before exiting, it will prompt you whether you want to save. If not, press N, or vice versa, press Y. Then it will let you confirm the name of the file you want to save, confirm or modify and press ENTER. If you have not modified and accidentally pressed the save key, you can press CTRL +c to cancel when requesting confirmation of the file name.

Cut and paste

To cut an entire line, use CTRL+K (Hold down CTRL and press the K key). The line where the cursor is located disappears. To paste it, simply move the cursor to the location you want to paste, and then press Ctrl+u. To move multiple lines, just press the ctrl+k a few more times to cut down the content you need to move, and then press CTRL +u to paste all the content you just cut. If you want to use more precise cut control, you need to mark the text. Move the cursor to the beginning of the text you want to cut, and press CTRL+6(or alt+a). Then move the cursor to the end of the text you want to cut: The text that was marked is anti-white. To undo a text marker, simply press CTRL +6again. Use Ctrl+k to cut the tagged text and paste it with ctrl+u.

Search for specific text

When you want to search for a particular text, it's easy tothink of it as "whereis" rather than "search". Just press Ctrl+w, type the string you want to search for, and then press ENTER. To search for the same string again, you can press alt+w directly.

Note: In the Nano help document, Ctrl-key is represented as a caret (^), so Ctrl+w is written as ^w, and so on. The alt-key is represented as a m (from "Meta" ), so Alt+w is written as a m-w.
