In Linux, the full name of devel is develop, which means "development" in Chinese. It refers to the development package of the corresponding software package; it contains all the necessary files for developing programs using this package, which at least includes header files and link libraries. , some also include development documentation or demonstration code. Non-devel packages only contain dynamic libraries and configuration files that allow the program to run.
#The operating environment of this tutorial: linux5.9.8 system, Dell G3 computer.
When installing packages on RHEL, you often see two packages with the same name: one with and without the devel suffix. For example:
elfutils-libelf.x86_64 : Library to read and write ELF files elfutils-libelf-devel.x86_64 : Development support for libelf
So what does devel mean?
devel is the abbreviation of develop, which means development. The package with devel is the development package, which is the development package of the corresponding software package.
The difference between devel packages and non-devel packages:
Packages without devel suffix usually only contain dynamic libraries and configuration files that allow the program to run. .
The package with devel suffix contains all the necessary files for developing programs using this package. Such as header files, etc. Sometimes devel packages also include static libraries.
devel package is mainly for development, including at least the following two things:
1. Header file
2. Link library
Some also contain development documents or demonstration code.
Take glib and glib-devel as an example:
If you install a program developed based on glib, you only need to install the glib package.
But if you want to compile source code using glib, you need to install glib-devel.
Note:
Note that python-dev or other *.devel software are generally some header files or cpp files written in C language, often other modules or this When compiling the modules we write ourselves, we need to rely on these *-devel software packages

The five core components of the Linux operating system are: 1. Kernel, 2. System libraries, 3. System tools, 4. System services, 5. File system. These components work together to ensure the stable and efficient operation of the system, and together form a powerful and flexible operating system.

The five core elements of Linux are: 1. Kernel, 2. Command line interface, 3. File system, 4. Package management, 5. Community and open source. Together, these elements define the nature and functionality of Linux.

Linux user management and security can be achieved through the following steps: 1. Create users and groups, using commands such as sudouseradd-m-gdevelopers-s/bin/bashjohn. 2. Bulkly create users and set password policies, using the for loop and chpasswd commands. 3. Check and fix common errors, home directory and shell settings. 4. Implement best practices such as strong cryptographic policies, regular audits and the principle of minimum authority. 5. Optimize performance, use sudo and adjust PAM module configuration. Through these methods, users can be effectively managed and system security can be improved.

The core operations of Linux file system and process management include file system management and process control. 1) File system operations include creating, deleting, copying and moving files or directories, using commands such as mkdir, rmdir, cp and mv. 2) Process management involves starting, monitoring and killing processes, using commands such as ./my_script.sh&, top and kill.

Shell scripts are powerful tools for automated execution of commands in Linux systems. 1) The shell script executes commands line by line through the interpreter to process variable substitution and conditional judgment. 2) The basic usage includes backup operations, such as using the tar command to back up the directory. 3) Advanced usage involves the use of functions and case statements to manage services. 4) Debugging skills include using set-x to enable debugging mode and set-e to exit when the command fails. 5) Performance optimization is recommended to avoid subshells, use arrays and optimization loops.

Linux is a Unix-based multi-user, multi-tasking operating system that emphasizes simplicity, modularity and openness. Its core functions include: file system: organized in a tree structure, supports multiple file systems such as ext4, XFS, Btrfs, and use df-T to view file system types. Process management: View the process through the ps command, manage the process using PID, involving priority settings and signal processing. Network configuration: Flexible setting of IP addresses and managing network services, and use sudoipaddradd to configure IP. These features are applied in real-life operations through basic commands and advanced script automation, improving efficiency and reducing errors.

The methods to enter Linux maintenance mode include: 1. Edit the GRUB configuration file, add "single" or "1" parameters and update the GRUB configuration; 2. Edit the startup parameters in the GRUB menu, add "single" or "1". Exit maintenance mode only requires restarting the system. With these steps, you can quickly enter maintenance mode when needed and exit safely, ensuring system stability and security.

The core components of Linux include kernel, shell, file system, process management and memory management. 1) Kernel management system resources, 2) shell provides user interaction interface, 3) file system supports multiple formats, 4) Process management is implemented through system calls such as fork, and 5) memory management uses virtual memory technology.
