Find Name/OS
This tutorial has examples for four versions of UNIX: Linux, Oracle’s Solaris, Apple’s Macintosh OS X and IBM’s AIX
Tutorial scenario

You are logged into a UNIX server. You know nothing about the server, not the version of the operating system, not its hardware configuration, not even if it is used to run your application. There might be documentation with information on this server. But, you would prefer to find out as much as you can by running various commands. Or perhaps you want to check the documentation.

This tutorial gives examples for four versions of UNIX: Linux, Oracle’s Solaris, Apple’s Macintosh OS X and IBM’s AIX.

Your Inventory Document
Every organization has some sort of inventory documentation. These will vary from simple spreadsheets to elaborate databases with web-based interfaces. The decision about which data is
worth gathering and storing will also vary from organization to organization. Here is a list of items you may include on your inventory document.  This tutorial will show how to determine each of these pieces of information.
FQDN (Fully Qualified Domain Name)
IP address
Default router
MAC address, primary interface
Secondary IP address, if applicable
Secondary MAC address, if applicable
Name service order
Operating system
OS release level
OS version
Machine hardware class
Processor type
Hardware implementation, if applicable
Number of CPU
CPU type
CPU clock speed
Total memory
