Are the operating systems UNIX and Linux easy to use? [closed]

When we think of free operating systems we tend to think overwhelmingly of the big hitters (all GNU/Linux) like Debian, Ubuntu, Fedora and Mandriva and then of those niche distros that have been designed for low end systems or for specialist purposes like security and forensics. But Oranges are not the only fruit.

Which Is Right For Me: Windows Hosting or Linux – Unix Hosting? By Marcus Lim We all have our preferences when it comes to operating systems some people prefer one of the many flavors of Windows, while others prefer one of the several distributions of Linux. It is all the matter of what works best for you.

I’m looking for an infrastructure which ideally should be maintained as following:

Several (virtual) operating-systems (linux and windows as well) should run on a server simultaneously and be accessible over the local network from heterogeneous clients (such as linux, os x and windows operating systems running on a desktop computer).

The aim is that it doesn’t matter which client device in the l

Important Unix Commands That You Should Know By Bernard Peh Unix is one of the most important operating system today. Its powerful features, scalability, strong security, and support for multiple users have made it the top choice operating systems for server, workstations and mainframes. It is good to have some knowledge of Unix commands especially if your web host is Unix/Linux based.

The man pages and programmer documentations for the socket options SO_REUSEADDR and SO_REUSEPORT are different for different operating systems and often highly confusing. Some operating systems don't even have the option SO_REUSEPORT.

Unix based operating systems like Linux offer a unique approach to join two discrete commands, and generate a new command using the concept of pipe(lines). For example, consider command1|command2. Here, whatever output is generated by the first command becomes the standard input for the second command.

Is it possible to capture packets without superuser?

This is what I see in the wikipedia article:

In some Unix-like operating systems, a user must have superuser privileges to use tcpdump because the packet capturing mechanisms on those systems require elevated privileges. However, the -Z option may be used to drop privileges to a specific unprivileged user after capturing has been set up.

As expressed earlier, there are more benefits to using this kind of web hosting. Some more points included here.  

We love Linux, us. We breathe it, eat it, and install it on anything that can add two numbers together. But we're also fans of other free software operating system projects - large or small - and we love to watch them improve.
