Amazon Linux vs Linux: What are the differences?
Key Differences between Amazon Linux and Linux
Amazon Linux is a Linux distribution specifically designed and optimized for use on Amazon Web Services (AWS) cloud instances, while Linux is a general term referring to the family of open-source Unix-like operating systems. Here are the key differences between the two:
Kernel Customization: Amazon Linux uses a customized Linux kernel to provide better performance, scalability, and integration with AWS services. Linux, on the other hand, offers a more generic and community-supported kernel, which may not have the same level of optimization for cloud environments.
Package Management: Amazon Linux uses the
yumpackage manager, which is based onrpm, making it easier to install, update, and manage software packages specifically for Amazon Linux instances. Linux distributions, on the other hand, use various package managers likeapt(Debian-based),dnf(Fedora-based), orzypper(openSUSE-based), each with its own set of commands and package repositories.Lifecycle Management: Amazon Linux follows a specific lifecycle management model where major versions are maintained for up to 5 years, and minor versions are released every six months with regular security updates. In contrast, Linux distributions have different support policies depending on the specific distribution, but they generally provide long-term support for major releases and regular updates.
Default Configuration: Amazon Linux comes pre-configured with optimized settings and packages that are tuned for AWS environments, providing a seamless experience when running applications on AWS. Linux distributions offer more flexibility in terms of customization and configuration, allowing users to tailor their systems to specific needs.
Backward Compatibility: Amazon Linux is highly backward compatible, ensuring that applications built on previous versions continue to work without major modifications. Linux distributions may have slightly different configurations and libraries, which may require some adjustments when migrating applications between different distributions.
Integration with AWS Services: Amazon Linux is tightly integrated with various AWS services, providing deep integration and optimized performance when running applications on AWS cloud instances. Linux, as a general-purpose operating system, does not have the same level of integration with AWS services out of the box, although it can still be used to run applications on AWS with some additional configuration.
In summary, Amazon Linux is a specialized Linux distribution optimized for AWS, offering a customized kernel, specific package management, lifecycle management, pre-configured settings, high backward compatibility, and deep integration with AWS services.
Netdata introduces Linux eBPF (Extended Berkeley Packet Filter) monitoring. With this enabled, monitor real-time metrics of Linux kernel functions and actions from the very same monitoring and troubleshooting dashboard used for watching entire systems, or even entire infrastructures.
This collector uses eBPF to monitor system calls inside your operating system’s kernel. For now, the main goal of this plugin is to monitor IO and process management on the host where it is running.
If you have a file (demo.txt) that has 3 columns:
Column-1 Column-2 Column-3
Row-1a Row-2a Row-3a
Row-1b Row-2b Row-3b
Row-1c Row-2c Row-3c
Row-1d Row-2d Row-3d
Row-1e Row-2e Row-3e
and you want to only view the first column of the file in your CLI, run the following:
awk {'print $1'} demo.txt
Column-1
Row-1a
Row-1b
Row-1c
Row-1d
Row-1e
If you want to print the second column of demo.txt, just replace $1 with $2
