Linux 批量处理dos2unix
在 windows 下编辑过的文件一般都会被保存为 dos 式, 而 mac os x 和 *nix 类系统一般都是使用 unix 式, 在windows下编辑过的文件在*nix下打开,会被加上^M, 然后造成程序出问题。 所以需要将文件的式从dos转换成unix. 可以使用的工具是dos2unix,使用命令如
在 windows 下编辑过的文件一般都会被保存为 dos 格式, 而 mac os x 和 *nix 类系统一般都是使用 unix 格式,

所以需要将文件的格式从dos转换成unix.
可以使用的工具是dos2unix,使用命令如下:
因为文件的数量太大,所以需要批量的来导。
这里就可以使用find 命令。
find . -type f
然后使用-exec参数 来运行某些命令。
find . -type f -exec dos2unix {} \;
注意dos2unix与{}之间有一个空格。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.

Using python in Linux terminal...

Regarding the problem of removing the Python interpreter that comes with Linux systems, many Linux distributions will preinstall the Python interpreter when installed, and it does not use the package manager...

Multithreading in the language can greatly improve program efficiency. There are four main ways to implement multithreading in C language: Create independent processes: Create multiple independently running processes, each process has its own memory space. Pseudo-multithreading: Create multiple execution streams in a process that share the same memory space and execute alternately. Multi-threaded library: Use multi-threaded libraries such as pthreads to create and manage threads, providing rich thread operation functions. Coroutine: A lightweight multi-threaded implementation that divides tasks into small subtasks and executes them in turn.

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.

To open a web.xml file, you can use the following methods: Use a text editor (such as Notepad or TextEdit) to edit commands using an integrated development environment (such as Eclipse or NetBeans) (Windows: notepad web.xml; Mac/Linux: open -a TextEdit web.xml)
