Use GDB to debug programs and gdb to debug programs
GDB (GNU Debuger) is a powerful Debugger in Linux. GDB allows you to view the internal structure of the program, print the variable value, set the breakpoint, debug the source code in a single step, modify the variable value during running, track the path, switch the thread, and display the assembly code.Compile
To use GDB for debugging, you must add the

Program Have you found that database data is frequently read repeatedly during computing (especially during multi-user computing ?! This is the primary killer of database processing program performance.
Some people say that before writing a programAlgorithmMake sure that the data records are read in batches and at one time. However, this is often not possible because complicated programs are close to the logical p

Is to write a short program, print your own code. In my understanding, metadata or file operations should not be used here. You must use the program code to generate a string exactly the same as your own code. I have written several versions, and the results of these programs are printed with the Code itself. You can try it and entertain yourself.

), SendMail is the program that the hacker focuses on, because SendMail is running as root and the code is large and prone to problems.
Almost all Linux distributors use SendMail as their default configuration, with only a handful of postfix or qmail as optional packages. However, few Linux distributors use SendMail on their mail servers. Both SuSE and red Hat use a qmail based system.
SendMail does not necessarily have to be completely replaced by other p
In the previous chapter, we mainly learned how an independent program works on the system, but when we actually write the program, we find that the program sometimes interacts with the IO device or other programs. This chapter focuses on the knowledge of how the program interacts with IO devices.The interaction between the program and the IO device is often seen, such as with disks, keyboards, and networks. The UNIX system is designed with all the fil
