Introduced Do you know that linux® is now the world's second server operating system? Today, does your application run on Linux? If not, this article will give you tips and tricks to guide you when porting your application to Linux. This article is based on the experience of software engineers who come from independen

A relatively safe Internet server, as an open-source operating system, once a security vulnerability is found in the Linux system, volunteers from around the world on the Internet will actively fix it. However, system administrators often cannot obtain and correct information in a timely manner, which gives hackers an

Beginners of Unix (including Linux) are often confused and don't understand what the directory structure means. For example, there is a subdirectory/bin underneath the root directory that holds the binaries. However, the/USR subdirectory also contains/usr/bin, as well as/usr/local/bin, which is also used to store binaries, and some systems even have/opt/bin. What's the difference between them?

good.Mainstream Linux distributions provide an excellent package management system that includes tools to access and search the software library on the Internet. Publishers actively maintain these repositories for the community, so Linux system administrators rarely need to jump out of the default Package manager on t

The Iconv command is a file-encoded reload tool that runs on the Linux/unix platform. When we look at the text file in the Linux/unix system shell, we often find that the file is garbled in Chinese, this is due to the encoding of the text file and the current operating

The answer is not good. Why, because they do not know the principle. In fact, the principle is very simple. You can judge this only when macro definitions are added to the compiler parameters or makefile. For example, if the compiler sets macro is_windows, you can use it. It cannot be used without setting. However, I am sure that various compilers have built-in macros, such as cl.exe of MS vc, GNU gcc of Linux, which have different built-in macros

What role does the Unix/linux kernel play in the system? Not only FreeBSD systems, each operating system has a kernel---from MS-DOS, Windows to advanced terminal mainframes, but various systems have different attitudes towards the kernel, and some systems have spent a lot of time hiding the kernel from the user. Both
