In the past, I really didn't play Linux, and I always felt that my classmates who played Linux all day were Daniel. Today, internships in the company need to telnet to the Linux server, all the code is to be completed on the Development Board, so forced to have to set the heart to learn the Linux system of various operations. I now use the remote login software is putty, so a simple summary of the commonly used putty instructions, convenient for later review.

1. Putty Introduction

　　With the popularity of Linux in server-side applications, Linux system management is increasingly dependent on remote. Among the various Telnet tools, putty is one of the great tools. Putty is a free, Telnet, rlogin, and SSH client under the Windows 32 platform, but features no less than the business Telnet class tool.

　　 using it to remotely manage Linux is very useful, and its main advantages are as follows:

• Completely free of charge;

3. Introduction of Putty common Operation instruction

Before introducing the instructions for Putty, let's briefly introduce the shell (not the shell sort here).

What is a shell? the main interface between the operating system and the outside is called the shell. Perhaps this is not a very good understanding, for a simple example. The most common cmd command line, which is a shell under the Windows operating system. To put it bluntly, my understanding of the shell is that the shell refers to the interface that the developer provides to the customer, which makes it easier for the customer to use their virtual hosting service better. The shell is divided into two categories: the graphical interface shell and the command-line shell. This article mainly deals with the command-line shell in Putty.
