Ubuntu is much more faster over Windows and helps to get software and other utilities easier and within a short span of time compared to Windows.

Ubuntu helps to get robustness and resiliency over Windows. Ubuntu runs faster than Windows on every computer that I have ever tested. LibreOffice (Ubuntu's default office suite) runs much faster than Microsoft Office on every computer that I have ever tested.

I liked manjaro a lot, the huge support it has and the variety of tools it provides is just awesome. But due to its parent platform being Arch Linux it has bleeding-edge technology and that meaning, we get updated 'daily', and if we keep updating the system daily, due to the bugs in the recent updates the system sometimes used to crash, this made the OS really unstable. However, one can avoid such crashes using periodical and careful system/package updates. I now use LinuxMint which is based on Ubuntu, and this OS is completely stable with reliable(mostly tested) updates. And, since this OS is backed up by UBUNTU the concerns/questions one can encounter while using the OS can be easily rectified using the UBUNTU community, which is pretty good. Though this is backed up on UBUNTU it most certainly does NOT include the proprietary stuff of UBUNTU, which is on the bright side of the OS. That's it! Happy Computing.

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
