Every admin knows how to retrieve information about the system on which they are working. How many cores does the CPU have? cat /proc/cpuinfo! Is eth3 a gigabit interface? ip l sh! But instead of many tools, you can just use one: inxi [1].

Suppose I need an overview of a machine with which I don't normally work. Then, I call inxi without any parameters and get some basic information about the hardware (CPU, clock speed, RAM, and disk size) and the system (kernel and shell processes). If I want to see a few details, the -F parameter provides information on the video and audio hardware, partitioning, RAID, temperatures, and fan speeds (Figure 1).

If I'm only interested in a particular component, I can target this with specific parameters, such as -C, -A, and -G, which stand for information on the CPU, audio, and graphics, respectively. Information on the RAM is returned after a (lowercase!) -m, which takes some getting used to.
