If a new character is passed in the 0.2 s, the character will be lost.As a result, the developers thought of a way to solve this problem, that is, adding two end characters after each line.

A long time before carriage return and line feed, the old-fashioned telex typewriter used two characters to start a new line. One character moves the slide frame back to the first place (called a carriage return, with an ASCII code of 0 D), and the other character moves a line (called line feed, with an ASCII code of 0 A) on the paper ). After the advent of the computer, the memory used to be very powerful... A long time before carriage return and li

CRLF Injection attacks are not as famous as other types of attacks. However, when a CRLF Injection Attack is performed on an application with security vulnerabilities, this attack is equally effective for attackers and can cause great damage to users. Let's see how these application attacks are implemented and what measures you can take to protect your organization. The meaning of CRLF is "carriage return/line feed", which means to press Enter. These are two ASCII characters, which are respectiv

Line feed conversion-general Linux technology-Linux technology and application information. For more information, see the following section. From windows to linux, some previously written script programs need to convert line breaks before they can run normally. The conversion method is actually very simple: Sed-e's/\ r // G' old_file> new_file You can. In windows, the line break is \ r \ n, and in linux/unix, It is \ n. \ R = 0x0d indicates the carriage return, \ n = 0x0a indicates the l

file, the disk is not directly written, but the buffer is written first. Data is written to the disk only when "the buffer is full" or "close the file;It seems that no buffer can be set. In this case, low-level I/O functions are used to directly operate the disk, which is slow. It is not a standard function and is not suitable for cross-platform operations.3.

passed in the 0.2 s, the character will be lost. As a result, the developers thought of a way to solve this problem, that is, adding two end characters after each line. One is "enter", which tells the typewriter to position the print head on the left boundary, and the other is "line feed", which tells the typewriter to move the paper down one line. This is the source of "line feed" and "Carriage Return". T

In addition, section 8.7 of Linux kernel source code scenario analysis and section 3.9 of operating systems: design and implementation (section 3rd in version 3.8) all of them provide a good introduction to the concepts and history of terminal devices. In addition, the introduction to terminal devices is also introduced in modern operating system. The text content is roughly the same as that of operating systems: design and implementation.
