The usage of the nano Editor-Linux Release Technology-Debian information. The following is a detailed description. The nano editor has been tossing for a long time. Add it to your favorites. Easy to find
In the future, we basically need to edit files to implement different settings. So what should we use to set the configuration file? Use an editor, like notepad and WordPad in windows, let's talk about the default debian Editor-nano.
First, let's check if there is any nano on the network.
There is very little nano information on the network, so I will explain how to use nano.
Let's take the network configuration file editing as an example.
GNU nano 1.2.4, nano version File: the absolute address of the File opened by/etc/network/interfaces
The following is the content of the opened file.
# This file describes the network interfaces available on your system
# And how to activate them. For more information, see interfaces (5 ).
# The loopback network interface
Auto lo
Iface lo inet loopback
# The primary network interface
Auto eth0
Iface eth0 inet static
Address 192.168.254.20
Netmask 255.255.255.0

^ G Get Help ^ O WriteOut ^ R Read File ^ Y Prev Page ^ K Cut Text ^ C Cur Pos
^ X Exit ^ J Justify ^ W Where Is ^ V Next Page ^ U UnCut Txt ^ T To Spell
These are help columns. Haha ^ G indicates pressing ctrl + g together, haha
^ G Get Help: press ctrl and G at the same time to call up the Help menu.
Let's give it a try.
After I click it, I bring up the Help menu. I will give you the shortcut key list below. Let's try it.
Vi has always been called the most powerful editor, but gentoo and debian chose nano as the default editor.
Freebsd chose ee as the default editor. I believe that freebsd and redaht are compared in the eyes of professionals,
There is nothing to show off about redhat. Why don't they choose vi because vi operations are complicated?
The so-called simple editor nano is simple and easy to use.
In fact, it's not simple at all. It's just nano's modest.
Here, I declare ^ to indicate the ctrl key on the keyboard. The last one should be clear as long as it is a programmer. ^ G indicates pressing ctrl and g at the same time.

Well, the nano editor will say so much.
Next, let's talk about the basic configuration files and locations.
The first is to open the efficient input location of the command line
I saw the advanced command line completion, and I don't need to remember the software package name. Oh, it's nice.
Why is ls out of color? Have you seen the color in redhat? let's change it.
No, blue is a directory, white is a file, and green is a file that can run.
Cnrot:/# ll
-Bash: ll: command not found
Tell us ll doesn't have this command
Let's make a custom command.
Remember to log out before it takes effect. You do not need to restart it.
No
No, this is a custom command.
Now, let me tell you the location of several files.
If you cannot find
First, the network configuration file/etc/network/interfaces
GNU nano 1.2.4 File:/etc/network/interfaces Modified
# This file describes the network interfaces available on your system
# And how to activate them. For more information, see interfaces (5 ).
# The loopback network interface
