Keep Linux accurate time
How to keep the correct time, how to use NTP and systemd to keep your computers in sync without abusing time servers. What is its time? Linux is weird when it comes to telling you the time. You may think that you are using the time command to tell you the time, but it is not because time is just a timer that measures how long a process has been running. To get the time, you need to run the date command. If you want to see more dates, you can run the cal command. Timestamps on files can also be a source of confusion, as there are two different ways to display them, depending on your distribution's default settings. Here is an example from Ubuntu16.04LTS: $l

Explore file types in Linux systems: ordinary files, directories, and special files
The following sections discuss the several file types in the Linux system and the basic functions of performing I/O when developing C language in Linux. However, in the process of giving examples and experiments, there are several file types in the Linux system, all of which revolve around ordinary files. File types in Linux Remember in Section 9, when we talked about the Unix system (Linux is a Unix-like system) that "everything is a file"? Most files in unix systems are ordinary files and directories, and these two types of files are also the most commonly used. For example, the /usr directory and the hello.txt text file above it belong to ordinary file types. In fact, linuxsite:infoq.cn, the Linux system divides all files into

In-depth understanding of patch files: diff instruction generation and common parameter analysis
The patch file is generated by the diff command (linuxdiff, svndiff, gitdiff, gitformat-patch). First, let’s introduce the diff command and its common parameters: diff: The function of diff is to compare the differences between two files and then record them, which is the so-called diff patch. Sentence format: diff [option] source file (folder) destination file (folder) Linux operating system is good, it is to patch the source file (folder) linux patch marge linux to make it into the destination file (folder) ), the term is "upgrade".

PDF operation guide for linux operating system
1. LibreOfficeDraw LibreOfficeDraw is an open source and free office suite that is not only suitable for Linux systems, but can also be used on Windows and MacOSX systems. LibreOfficeDraw official documents state that the system will be permanently free for enterprises and individuals, and the code will be fully open. For those who don't have too many special requirements for PDFs (such as just need to edit PDF documents), then this is a good tool. But if you have high requirements for PDF tools (such as needing to edit scanned documents), then Draw may no longer be an ideal tool. 2. PDFStudioPDFStudio is a commercial software that

Detailed explanation of two ways to merge git code
This kind of merge of gitMerge merges the history of two branches together. The existing branch will not be changed. It will compare the different files of both parties and cache them, generate a commit, and push. Advantages: safe, existing branches cannot be changed. Will be modified Disadvantages: It will more or less pollute the branch history, and it will increase the difficulty of understanding the project history when looking back at the project. Uses: Generally used for the public master main branch gitRebase. This kind of merger is usually called "rebase". It is to modify the commit history, compare the commits of both parties, then find out the differences and cache them, and then push them to modify your commit history. Pros: Project history will be very tidy Cons: Security and traceability are poor, you won’t be able to tell

Functions of the ping command and differences between Linux and Windows systems
The function of the ping command is to test the network connectivity between hosts. It sends out data packets based on the ICMP transmission contract to test the Linux network delay, and requires the other host to reply. If there is no problem with the network function of the other host and the firewall allows the traffic, Then the information will be replied to, and we will know that the other party's host system is online and running normally. However, it is worth noting that there are certain differences between Linux and Windows. The ping command under the Windows system will send out 4 requests and then terminate the command manually; while the Linux system will not terminate manually and requires the user to automatically press the key combination." Ctrl+c" to end, or add the -c parameter when initiating the command to limit the number of messages sent. Test environment: Ce

How to test network transfer rate in Linux using built-in tools or commands
In Linux, we can use some external tools or commands to test the network transmission speed. The following are some common methods: (picture source network, intrusion and deletion) 1. Use the ping command. The ping command can be used to test the network. Latency and packet loss rate, but it cannot directly detect the network transmission speed. We can indirectly measure the network transmission speed by sending a large number of data packets and observing the transmission time. The pings1472 target IP address command will send a 1472-byte data packet to the target IP address for Linux network latency testing. By observing the return time, we can determine the network transmission speed. 2. Use the iperf tool. iperf is a network performance testing tool that can be used to check

Linux operating system: a free, freely disseminated and stable multi-user network system
Linux is a free-to-use and freely disseminated Unix-like operating system. It is a multi-user, multi-task, multi-thread and multi-CPU operating system based on POSIX and UNIX. It can run major UNIX software tools, applications and network contracts. It supports 32-bit and 64-bit hardware. Linux inherits the network-centric design philosophy of Unix and is a multi-user network operating system with stable performance. Teachers from Lingyang Education said before that strictly speaking, the word Linux itself only refers to the Linux kernel, but in fact people have long been accustomed to using Linux to describe the entire operating system based on the Linux kernel but using various tools and databases of the GNU Project. included in linux
