In this tutorial we create a variety of dialog boxes in the Linux interactive shell script, the dialog box can be friendly to the operator in Linux, interested friends can refer to learning about.When you install new software in the terminal environment, you can often see the Information dialog box pop-up and need your input. The types of dialog boxes are Lockbox, checklist, menu, and so on. They can guide you in an intuitive way to enter the necessar
When you install new software in a terminal environment, you can often see the Information dialog box pop up and need your input. The type of dialog box has a password box, checklist, menu, and so on. They can guide you in an intuitive way to enter the necessary information, and the benefits of using such a user-friendly dialog box are obvious. As shown in the following illustration:
When you write an interactive shell script, you can use su

Let's take a look at the acceptTcpHandler function:
This function first calls anetTcpAccept to obtain the socket fd (the fd returned by the actual call: accept (s, sa, len) function) connected to redis from the client, and then calls the acceptCommonHandler () function, this function calls createClient () to create a redisClient * c instance. If the total number of connections of the current redis server does not exceed the maxi

After reading the second chapter of C ++ primer, we will sort out the const, pointer and reference, and the constexpr, auto, and so on.
1. Const must be initialized
const int i = 42;const int j = get_size();
Ii. Const and references1. constant reference (reference to a constant): bind a reference to a constant object.
const int ci = 42;const int r1 = ci;
2. In addition, a constant reference is allowed to bind a very large object, literal value or expression.
Int I = 42; const Int R1 = I; // bin
How to Make LVS and RealServer work on the same machine?1,573 read comments (no comments currently) More 0
We have a simple and inexpensive LVS-DR setting. Two servers run database services. These requests are directed to the servers or other servers on the local machine. Because pure4-layer scheduling, which is my favorite method. This time, I want to directly run the LVS service on these two servers. Not on other machines.
Therefore, keepalived is used for configuration and Master/Slave. Also

review? What can you do to make the process less painful if you're the developer who's having your code reviewed?
Remember that the Code isn' t you.Development is a creative process. it's normal to get attached to your code. however, the folks who are reviewing the Code generally aren't trying to say that you're a bad developer (or person) by pointing out something that you missed, or a better way of handling things. they're doing what they're supposed to be doing by pointing out better ways.
