探究Linux操作系统的多样性（linux的分支）
Linux is an open source operating system that offers variety, cost savings, and improved levels of security for computer users. It has a user-friendly interface and many features which make it an attractive choice for both individual and business users.
Linux is versatile, and can be used as both a desktop and a server. It is open source, meaning that anyone can inspect and modify the source code, and then customize the operating system to meet specific needs. Unlike closed source operating systems, users of Linux have the ability to customize their systems to the nth degree. This makes it possible for users to do everything from creating custom applications to integrating hardware devices and software packages to crafting their own operating system from scratch.
On the cost side, Linux is an attractive option thanks to its low maintenance costs and its cost-free nature. It is estimated that over 90% of Linux systems can be administered either on the cheap or for free depending on the user’s skill level and tools available.
Linux is also well known for its security. Many organizations that require high levels of security to protect sensitive data choose Linux as their primary operating system. Linux offers a variety of tools to protect against viruses, malicious programs, and other security threats. Additionally, Linux supports strong authentication protocols and offers a wide range of secure file sharing options. It also provides the ability to automatically detect and repair changes to system files.
The following code shows a very basic example of how Linux shell commands work.
# Create a new file
touch
# Create a new directory
mkdir
# Delete a file
rm
# Copy a file
cp
# Change a file’s permissions
chmod
The code above represents only a fraction of the multitude of Linux commands that can be used to customize the operating system. By working with Linux, users can customize their own systems to fit specific needs, use cost-effective tools, and enjoy improved security. As such, Linux is a great choice for users who want to get the most out of their computing experience.
