Docker is a platform that allows developers to build, run and manage applications in containers. Its core structure includes DockerEngine, mirroring and containers, client-server architecture, and namespace-based isolation mechanism. 1.DockerEngine is a core component, including a daemon running in the background (responsible for building images and running containers), a RESTAPI interface and a command line client (CLI). 2. Mirror is a static template that contains the application and its dependencies. The container is a running instance of the image. Multiple containers can originate from the same image, and the image is built through the Dockerfile. 3. Docker uses the client-server architecture, the CLI communicates with the daemon through the API, and can also connect to remote guards.

What is the difference between Linux and Unix?
The main differences between Linux and Unix are ownership, hardware compatibility, usage scenarios and support mode. 1. Ownership and License: Unix is mostly proprietary systems and needs to be used for a fee; Linux is open source and free. 2. Hardware compatibility: Unix usually binds to specific hardware platforms; Linux can run on multiple architectures. 3. Current uses: Unix is still used in enterprise-level mission-critical systems; Linux is widely used in cloud computing, embedded devices and personal projects. 4. Support method: Unix depends on vendor support; Linux has both community support and commercial support options. These differences are particularly significant in budgets, custom requirements, and infrastructure choices.

How to recursively change permissions for all files in a directory?
To recursively change permissions to all files in a directory and its subdirectories, use the chmod-R command. For example: chmod-R755/path/to/directory, where 755 means that the owner can read and write and execute, and the group and other users can only read and execute; the permission numbers are composed of read (4), write (2), and execute (1), such as 644 means that the owner can read and write, and other users can only read; if you need to distinguish file and directory permissions, you can set two commands separately: find/path/to/directory-typed-execchmod755{}\\; for directory, find/path/to/directory-typef-execchmod

How to remove duplicate lines from a file?
When deduplication of duplicate lines in files, you need to pay attention to key points such as retaining order and processing large files. 1. Use sort and uniq combination to quickly deduplicate, but it will disrupt the original order; 2. If the original order is to be preserved, it can be implemented by awk command; 3. When processing large files, you can use chunking processing, database import or memory optimization scripts; 4. Python scripts are suitable for medium-sized files and support more custom details; 5. Before deduplication, it is recommended to back up the file and check the impact of hidden characters. Just choose the appropriate method according to the specific needs.

What is the difference between $*, $@, and $# in shell scripts?
In shell scripts, special variables $#, $*, and @ are used to handle command line parameters and their behavior varies. 1.$# represents the number of parameters passed to the script, which is suitable for checking whether the number of parameters is correct; 2.$* treats all parameters as a whole string, and is connected by spaces by default, which is suitable for logging or passing parameters as a whole, but the original spaces or quotes may not be retained; 3.$@ treats each parameter as an independent string, retains original separation, which is suitable for traversing parameters or passing parameters with spaces such as file names. These variables should always be wrapped in quotes when using them to avoid problems caused by special characters.

What is a Git branching strategy like GitFlow?
GitFlow is a structured Git branch management strategy that is suitable for medium and large projects or teams with fixed release cycles. It improves code collaboration efficiency by defining well-defined branch types and merge processes. Its core contains two long-term branches: main is used to store production environment code and develop as an integrated branch; and three short-term branches: 1. Feature branches are separated from develop, merged back to develop after developing new functions; 2. Release branches are separated from develop, used to prepare for release versions, and finally merged into main and develop; 3. Hotfix branches are separated from main, and merged back to main and develop after emergency repair of online problems.
