How to Batch Add Users in Linux System
How to Batch Add Users in Linux System
Tutorial on the method of batch adding users in Linux system:When do we need to add users in large quantities? Sometimes we need dozens or more users to complete the same or similar tasks on the host. For example, we want to add a group of FTP users at the same time. These FTP users belong to the same group, but they are not allowed to log in to the server through the terminal or remote; Sometimes we may teach. For example, we have 50 students, and each student has an independent user name on the server, can log in to the system, manage his own account or complete some homework under his own authority;Batch user addition process:The process of adding users in batch is to import a file with contents written in strict accordance with the writing format of / etc / passwd through newusers to complete the process of adding users, and then import the user password file through chpasswd to complete the process of updating user passwords in batch;1. Newusers is a tool for adding users in batches;Its usage is very simple. Newusers is directly followed by a file; The file format is the same as / etc / passwd;User name 1: X: uid: GID: user description: user's home directory: shell usedgive an example:/bin/sh/bin/bash/sbin/nologin/bin/ksh/bin/tcsh/bin/csh/bin/zshExcept / SBIN / nologin, other types of shell can log in to the system; Nologin is mostly a "shell" used by virtual users, that is, although he is a system user, he does not have the permission to log in to the system; If you want to add such users, set their shell to / SBIN / nologin, such as the above example; You can read the corresponding reference documents about the user name, uid, GID and the user's home directory;2. Chpasswd batch update user password tool;Chpasswd tool is a tool to update user passwords in batches. It redirects and adds the contents of a file to / etc / shadow;Chpasswd fileHowever, the content of the document is not without agreement. It must be written in the following format without blank lines;User name: passwordUser name 1: password 1User name 2: password 2give an example:win00:123456win01:654321Batch add user instances:1. First, we create user files and password files;We will create the file userfile.txt containing the new user; the other is userpwdfile.txt setting the password for the newly added user;Then open the file userfile.txt with a text editor and add the following contents;The content format of the userfile.txt file is the same as that of / etc / passwd and must be written in strict accordance with the format of / etc / passwd. The users added above cannot log in to the system, but can be used for FTP login, but you have to open it in the configuration file of the corresponding FTP server to allow local users to have read and write permissions. If you want some of the above users to log in to the system, you can Change the shell analogy, such as / bin / bash; let's write the content of the password file userpwdfile.txt of the new user; the user name in the content of this file should be the same as the user name of userfile.txt; that is, we first added users from win00 to win09, and now we want to update the password for these users; for example, the following;win00:123456win01:654321win02:123321win03:qweewqwin04:googlewin05:adadwcwin06:wssceewin07:xxec32win08:543wewwin09:3ce3wf2. Batch adding users through newusers and chpasswd;In this way, even if the addition is completed, if you find the user's explicit password in / etc / passwd, you can map it to the / etc / shadow file name through the following command;

Analysis of System Composition and Architecture of LED Display Screen
Analysis of System Composition and Architecture of LED Display Screen
As a high-tech product, LED display has attracted great attention. The intelligent full-color display, which is controlled by computer and integrates light and electricity, has been applied in a wide range of fields. The pixel points adopt LED light-emitting diodes, and many light-emitting diodes are arranged in a dot matrix to form an LED array and then an LED screen. Through different LED driving modes, images with different effects can be obtained. Therefore, the advantages and disadvantages of LED driver chip play an important role in the display quality of LED display screen. LED driver chips can be divided into general chips and special chips.General purpose chips are generally used for low-end products of LED display screens, such as indoor single and dual color screens. The most commonly used general chip is 74HC595, which has the functions of 8-bit latch, serial shift register and three state output. Each channel can output 35mA non constant current at most.Because LED is a current characteristic device, that is, on the premise of saturated conduction, its brightness changes with the change of current, not with the change of voltage at both ends. The biggest feature of the special chip is to provide constant current source output, ensure the stable driving of LED and eliminate the flicker of LED. With the characteristics of high output current and constant current, it is suitable for occasions requiring high current and high image quality, such as outdoor full-color screen, indoor full-color screen, etc.LED driver chip series products for LED display smt5026.smt5026 has built-in CMOS shift register and latch function, which can convert serial input data into parallel output data format.Part II: system architecture of LED display screen(1) Display unitThis is the main part of the LED display screen, which is composed of luminous materials and driving circuits. The indoor screen is the unit display board of various specifications, and the outdoor screen is the unit box.(2) Main controllerThe function is to buffer, transform and reorganize the input RGB digital video signal, and generate various control signals.(3) Switching power supplyThe purpose is to change 220V AC into various DC to supply various circuits.(4) Transmission cableThe display data and various control signals generated by the main controller are transmitted to the screen body by twisted pair cable.(5) Scan controllerThe function of the circuit board is to buffer data and generate various scanning signals and duty cycle gray control signals.(6) Special display card and multimedia card (video card)In addition to the basic functions of the computer display card, the LED full-color display card also outputs digital RGB signals, line, field, blanking and other signals to the main controller. In addition to the above functions, the multimedia card can also change the input analog video signal into digital RGB signal (i.e. video acquisition).(7) Other signal sources and their external devices

Analysis of Common Causes of Notebook Screen Darkness
Analysis of Common Causes of Notebook Screen Darkness
If you find that the notebook's display screen (TFT) is very dark when you turn it on, the contrast and dark notebook screen is still very dark and can't be seen clearly. That's the screen darkHow does the screen darken? There are four common situations:The first is the problem of the lamp tube. The aging or short circuit of the lamp tube will darken the display screen. If the lamp tube has a problem, it can only be replaced by a professional maintenance company. The aging and short circuit of the lamp tube rarely occur. The aging is generally due to long-term use or collision during use (the service life of the lamp tube in normal use can reach about 3 5 years). The short circuit is caused by the metal in the screen shell, If the screen shell is broken, use it carefully to prevent short circuit.The second is that the main board has no voltage for the high-voltage board. Problems, aging or short circuit of the main board will occur. Most of them can be repaired. It is not necessary to replace the main board.The third is the aging or burning of the high-voltage board, or the loosening and burning of the power connection line of the high-voltage board. The screen darkness caused by the high-voltage board is more common, because the high-voltage board works at high temperature for a long time, the chip will be easier to age or burn outThe fourth is the broken screen line, which is often the cause of screen darkness, because NB is folding. Opening and closing the screen too hard will wear the screen line, and frequent use will easily cause the broken screen line.Generally, problems with the graphics card will not cause the screen to be dark. Most of them are flower screen or no display. In addition to the replacement of the lamp tube, the replacement of a non original high-voltage plate may cause the dimmable brightness of the LCD screen to fail (the impact depends on the individual). Generally, the high-voltage plate can be repaired.Conclusion: generally, it is not recommended to disassemble and repair by yourself.
Comments and Interpretation on the Group Standard of General Technical Specification for Mini Led Co
Comments and Interpretation on the Group Standard of General Technical Specification for Mini Led Co
June 15, 2020 is a big day of concern and historical significance for the LED display industry: the group standard of general technical specification for mini led commercial display screen formulated under the leadership of Shenzhen lighting and display engineering industry association has been officially implemented.Here is a comment and interpretation on the key core contents of the group standard of the general technical specification for mini led commercial display screen (hereinafter referred to as the technical specification), some of which are our views on the future development of mini LED technology. There is something wrong. I hope you can criticize and correct it.Anyway, it's better to have a definition than not. In terms and definitions 3.1 of the technical specification, "led device with chip size between 50-200 M." and in 3.2, "unit composed of mini LED pixel array and driving circuit with pixel center spacing of 0.3-1.5mm." I think this sentence is well defined and constitutes a simple and accurate judgment of mini LED technology.So how to interpret the above two sentences?Firstly, in 3.1, we see the references of "chip" and "led device", which shows that mini LED technology is composed of LED chip technology and LED chip packaging technology. Just as we mentioned earlier, LED chip technology and LED packaging technology are the most important technologies in LED display panel technology. LED chip can never be separated from the protection of LED packaging technology for its function and service life. It is of great significance to clarify the wrong orientation of "de encapsulation" or "non encapsulation" advocated by downstream enterprises in the industry.Secondly, in the final version of the technical specification, the text "composed of two or more groups of red, green and blue light-emitting chips" appearing before "LED devices" in item 3.1 of the preparation process is removed, and the pixel center spacing range of "0.3-1.0mm" is enlarged to "0.3-1.5mm" in 3.2 to maximize the interests of all parties, So that the originally excluded SMD technology can have the opportunity to compete with other technologies on the same stage, reflecting the principle of "Leniency". The final version determines that SMD packaging technology, 2in1 packaging technology, 4in1 packaging technology, nin1 packaging technology and cobip integrated packaging technology can be used as mini LEDs to eliminate discrimination and stand on the same starting line.In addition, we also pay attention to the reference of "separation technology of bracket type limited integrated lamp driver and integration technology of non bracket type integrated packaged lamp driver" in the classification of packaging technology in "4 display screen classification" in the technical specification, which is also the first classification method in all standards on LED display screen, which is of extraordinary significance and far-reaching impact.Among the packaging technologies of mini LEDs that have been shortlisted, the technologies that belong to the separation of bracket type limited integrated lamp drivers include 2in1, 4in1 and nin1 packaging technologies, which can also be collectively referred to as coblip (COB limited integrated pixel packaging) technology; At present, cobip technology is the only one that belongs to the non bracket integrated packaging lamp drive in one technology. Of course, there will be updated technology intervention soon. SMD is also an LED packaging device. Although it has nothing to do with the above integration concept classification, it also belongs to the bracket type lamp driver separation technology. In fact, this classification distinguishes the technical concepts of "separation and integration" and "lamp drive separation and lamp drive integration". For the future development of mini LED technology, PK is exactly this classification concept. These concepts represent different technical solutions and diversified technical paths to realize Mini led.In section 5.1.8 of the technical specification, the PZ index of pixel out of control rate and whole screen pixel out of control rate uses ppm unit, that is, million level (as shown in Figure 1). In the field of LED display, the specification of pixel out of control rate has appeared a million level index for the first time, which is of epoch-making significance. In other words, LED display products have the ability to compete with LCD and other display products in pixel failure control for the first time. In the past, we only had 10000 level technical capacity, but now we have cobip million level technical capacity.In addition, we see a continuous requirement for 10000 hours of cumulative use. What is the concept of 10000 hours? If it is used for 8 hours a day, it takes 3.4 years to be bound by the standard; If it is used 24 hours a day, it will last for 1.14 years.We believe that this index requirement is very important for the future 4K and 8K ultra-high definition video display products, mini led and micro LED display products. It is the most basic and important index requirement. Therefore, this index has considerable strictness and technical operation difficulty, reflecting the "strict" hurdle threshold difficulty of the finalists. In the future, Bo Zhong will play a game between the bracket type limited integrated lamp drive separation technology and the non bracket type integrated package lamp drive integration technology.Figure IIt's not that SMD, 2in1, 4in1 and nin1 packaging technologies are ten thousand level technologies, so they can't do Mini LED technology. It's just that when facing the million level index requirements of project bidding, they should have enough psychological preparation and be able to bear the maintenance cost paid by customers according to the technical requirements of the bidding documents.4 About Mini led and micro LED productsAccording to the definition in the technical specification, the pixel spacing of 0.3mm is still the category of mini led, so there are no micro LED technology products in the LED display industry, which clarifies the industry chaos. The pixel spacing is enlarged to 1.5mm. As long as the size of the LED chip we use meets the condition of 50-200 m, it can be called mini LED products. On the contrary, the scope of mini LED products has become larger, overlapping the scope of some small spacing display product concepts in the past.For the technical specification, someone told me, "it is specially tailored for 4in1 packaging technology", but I don't think so. For whom, only the best technology has the final say. In short, it is an excellent model of technical specification that is fair and reasonable, wide in and strict out, reflects technological progress and meets the future development direction.
