Configuring the Hardware Settings

This chapter covers viewing interrupts. It focuses on /proc/interrupts, CPU info viewing (/proc/cpuinfo), and viewing the physical memory installed. It also looks at /proc/meminfo, the free command, viewing swap memory, and adding and removing additional swap memory using the dd, mkswap, swapon, and swapoff commands. The raid status (viewing/proc/mdstat) is outlined, as is the /dev devices directory, the /proc virtual directory, the lsmod command and its usage, the modprobe command and its usage, and the lspci command and its usage. The /proc directory is a virtual filesystem that is created upon boot up, which stores various items of hardware information about a system.

Navigating through the various directories and using these commands is very informative, and allows you to retrieve hardware information in a Linux environment.

We will cover the following topics in this chapter:

  • Viewing CPU, RAM, and swap info
  • Interrupts and devices
  • Modules
