Sed (stream editor)
Function Description: Uses scripts to process text files.Syntax: sed [-hnV] [-e Note: sed can process and edit text files according to script instructions.Parameters:-E -F -H or -- help displays help.-N or -- quiet or -- silent only displays the results after script processing.
-V or -- version displays version information.
Sed Working principle:
Sed is a non-interactive stream editor.
Java IO (input output) stream 1. The buffer of the upstream stream 1. What is the buffer, also known as the cache, is a part of the memory space. That is to say, a certain amount of storage space is reserved in the memory space, which is used to buffer input or output data. This reserved space is called a buffer zone. The buffer zone is divided into the input buffer zone and the output buffer zone based on

1. Copy a text file
Copy the text file from disk G to disk D.
That is, read the data of text files in the G drive and write the data to drive D-> write-in-connection
The cut is to delete the file on the original disk after the original disk is read and written.
If a file is in use, it cannot be deleted. Therefore, be sure to associate these

No matter whether the correct or wrong data is output to the screen by default, the information displayed on the screen will be messy! Can we separate these two data sets through some mechanisms? Of course! That is the function of data stream redirection! Data Stream redirection can transfer standard output (stdout) and standard error output (stderr) to

When using xml-rpc, the server obtains client data mainly through the php input stream input instead of the $ _ POST array. So here we will mainly discuss php input stream php: // input
For a php: // input introduction, the PHP official manual provides a clear overview of it.
"Php: // input allows you to read raw POST data. it is a less memory intensive alternative to $ HTTP_RAW_POST_DATA and does not need

In the buffer zone, an array is encapsulated to provide external methods for Array Operations. These methods ultimately operate on the array badge.
Principle: extract data from the source and store it in the buffer zone. After the data is obtained, the system continues to
Waterfall stream-absolute positioning layout, which is different from floating Layout
1. Different la s:
Absolute positioning: Put all absolute positioning Li in a UL;
Floating layout: Multiple (generally three or four) UL distributions are placed in Li;
2. Ajax is different.
Absolute positioning: you only need to insert the JSON data from the request (of course, data in other formats) to ul. Then

OperationSometimes conversion between data and byte arrays is cumbersome. To avoid these boring conversions and simplified code, it is wise to use streamreader/streamwrite and binaryreader/binarywriter. Streamreader and streamwrite are derived from the textreader and textwriter classes respectively, and are automatically converted to Byte encoding. Bi
