Inxi – A Powerful Feature-Rich Commandline System Information Tool for Linux
============================================================


Inxi is a powerful and remarkable command line-system information script designed for both console and IRC (Internet Relay Chat). It can be employed to instantly deduce user system configuration and hardware information, and also functions as a debugging, and forum technical support tool.

It displays handy information concerning system hardware (hard disk, sound cards, graphic card, network cards, CPU, RAM, and more), together with system information about drivers, Xorg, desktop environment, kernel, GCC version(s), processes, uptime, memory, and a wide array of other useful information.

However, it’s output slightly differs between the command line and IRC, with a few default filters and color options applicable to IRC usage. The supported IRC clients include: BitchX, Gaim/Pidgin, ircII, Irssi, Konversation, Kopete, KSirc, KVIrc, Weechat, and Xchat plus any others that are capable of showing either built in or external Inxi output.

### How to Install Inxi in Linux System

Inix is available in most mainstream Linux distribution repositories, and runs on BSDs as well.

```
$ sudo apt-get install inxi   [On Debian/Ubuntu/Linux Mint]
$ sudo yum install inxi       [On CentOs/RHEL/Fedora]
$ sudo dnf install inxi       [On Fedora 22+]
```

Before we start using it, we can run the command that follows to check all application dependencies plus recommends, and various directories, and display what package(s) we need to install to add support for a given feature.

```
$ inxi --recommends 
```
Inxi Checking

### Linux System Monitoring with Inxi Tool

Following are few options used to monitor Linux system processes, uptime, memory etc.

#### Monitor Linux Processes Memory Usage

Get summarized system info in relation to total number of processes, uptime and memory usage:

```
$ inxi -I
Info:      Processes: 232 Uptime: 3:35 Memory: 3256.3/7879.9MB Client: Shell (bash) inxi: 2.2.35 
```

#### Monitoring Processes by CPU and Memory Usage

By default, it can help us determine the [top 5 processes consuming CPU or memory][1]. The `-t` option used together with `c` (CPU) and/or `m` (memory) options lists the top 5 most active processes eating up CPU and/or memory as shown below:

```
----------------- Linux CPU Usage ----------------- 
$ inxi -t c 
Processes: CPU: % used - top 5 active
1: cpu: 53.7% command: plugin-container pid: 3066
2: cpu: 20.0% command: java pid: 1527
3: cpu: 19.7% command: firefox pid: 3018
4: cpu: 4.6% command: Xorg pid: 2114
5: cpu: 3.0% command: cinnamon pid: 2835
```

```
----------------- Linux Memoery Usage -----------------
