The command xxd is useful when we need to convert the binary into a hexadecimal character array used in the C language.

Generally, files are divided into two categories: text files and binary files. It is easy to edit text files. notepad and ultraedit in windows are easy to use. There are also many tools for editing binary files in windows, ultraedit is also good, but what about Linux? Today, I finally found a good method, but the final source cannot be found.
First, create a binary file:

In linux, the tool xxd uses xxd to display a file in hexadecimal format. The specific options are as follows. -A: it automatically skips blank content. The default value is-c. It is followed by a number to indicate the number of bytes displayed in each row in hexadecimal format. The default value is 16 bytes. -G: Set to several bytes. The default value is 2 bytes. -L: the number of bytes displayed. -S: foll
Generally speaking, the file is divided into two major categories of text and binary files, text file editing is easy, Windows Notepad, UltraEdit are very useful, binary file editing under Windows also has a lot of tools, UltraEdit is good, but Linux?

The Cat command feature is used to display the contents of the entire file using no page-flipping function, so often and more commands are used, the cat command is to combine several files into a single file function.
More command function: let the screen when displaying full page pause, at this time can press empty bar once continue to display the next screen, or press Q key stop display.
Less command function: The less command is similar to the more command, and can be used to browse more th

Geometric modeling technology has been widely used in product development and manufacturing. However, for various reasons, there are still many products that are not described by the CAD model, and the design and manufacturer are facing the physical samples. In order to adapt to the development of advanced manufacturing technology, it is necessary to convert these physical objects into CAD models, so that they can be processed using advanced technologies such as CAD and CAM. At present, technolo
A reverse proxy (Reverse proxy) means that a proxy server accepts external connection requests and then forwards the request to a server on the internal network and returns the results obtained from the server to the external request-connected client. At this point, the proxy server behaves as a server.
