There are a variety of tools that a system administrator can use to check and monitor the health of their Linux system. This would include not only the physical hardware, but also the software and how many resources are being dedicated to running the installed services. In this tutorial, you will learn several commands to check overall health of your Linux system from the command line.

All code presented here is not compiler-specific, and all examples will be written in plain ANSI C++. Debates about pointers can stretch for miles, and you would need to go really far to master it all.
Android system architecture
The purpose of this tutorial is to explore the system architecture of the Android mobile operating system. This will give you a general idea of the various layers involved in Android and how they relate to each other. We will also talk about how Android relates to Linux itself.
Pax command examples on Linux
pax is an archive utility somewhere between cpio and tar. This is just because it is independent of the specific archive format, and supports a wide variety of different archive formats. It can perform simple tasks as creating a compressed archive of a selected directory or it can as much easily create a daily incremental backup.
Check libc version
The GNU C Library, often abbreviated to libc or glibc, is ordinarily installed out of the box on all major Linux distros. It is an essential library that many software packages will rely on in order to run properly or run at all. In case you need to check what version of libc is installed on your Linux system, we have you covered in this tutorial.
What is my processor architecture?
Knowing the architecture of your system’s processor is essential when picking an operating system to download and install. Certain editions of Linux and other operating systems are typically only made to work with a certain architecture, whether that be x86 (32 bit), x86-64 (64 bit), ARM (in the case of Raspberry Pi systems), etc. Furthermore, software that you are interested in running may only be designed to work with a particular architecture.
