CoreOS vs Linux: What are the differences?
Developers describe CoreOS as "Linux for Massive Server Deployments". CoreOS is designed for security, consistency, and reliability. Instead of installing packages via yum or apt, CoreOS uses Linux containers to manage your services at a higher level of abstraction. A single service's code and all dependencies are packaged within a container that can be run on one or many CoreOS machines. On the other hand, Linux is detailed as "A family of free and open source software operating systems based on the Linux kernel". A clone of the operating system Unix, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX and Single UNIX Specification compliance.
CoreOS and Linux can be primarily classified as "Operating Systems" tools.
Broadsheet, Deliveroo, and Rightech IoT Cloud are some of the popular companies that use Linux, whereas CoreOS is used by SoFi, Astronomer, and Instamojo. Linux has a broader approval, being mentioned in 25 company stacks & 126 developers stacks; compared to CoreOS, which is listed in 45 company stacks and 12 developer stacks.
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
