The\u00a0proc file system<\/a>\u00a0is a virtual file system that contains files that store information about processes and other system information. It is mapped to the\u00a0\/proc<\/code>\u00a0directory and mounted at boot time. A number of programs retrieve information from\u00a0\/proc<\/strong>\u00a0file system, process it and provide it readily usable for various purposes.<\/p>\n

Procinfo<\/strong>\u00a0is a simple command line utility for viewing system information collected from\u00a0\/proc<\/strong>\u00a0directory and prints it beautifully formatted on the standard output device. In this article, we will explain a number of\u00a0procinfo<\/strong>command examples in Linux.<\/p>\n

In most Linux distributions, the\u00a0procinfo<\/strong>\u00a0command should come pre-installed, if you don\u2019t have it, install it using following command.<\/p>\n

$ sudo apt install procinfo\t\t#Debian\/Ubuntu\r\n$ sudo yum install procinfo\t\t#CentOS\/RHEL\r\n$ sudo dnf install procinfo\t\t#Fedora 22+\r\n<\/pre>\n
The simplest example is to run\u00a0procinfo<\/strong>\u00a0without any arguments as shown.<\/p>\n

The\u00a0-d<\/strong>\u00a0flag allows for displaying statistics on a per-seconds basis rather than as total values.<\/p>\n
$ procinfo -d \r\n<\/pre>\n
To display statistics as totals, use the\u00a0-D<\/code>\u00a0flag as follows.<\/p>\n
$ procinfo -D\r\n<\/pre>\n
You can get continues updates on the screen and pause updates for N number of second (for instance\u00a05<\/strong>seconds in this command) using the\u00a0-n<\/code>\u00a0flag and press\u00a0q<\/code>\u00a0to quit in this mode.<\/p>\n
$ procinfo -n5 -H\r\n<\/pre>\n
To report \u201creal<\/strong>\u201d free memory similar to that showed by the\u00a0free utility<\/a>, use the\u00a0-r<\/code>\u00a0option.<\/p>\n
$ procinfo -r \r\n<\/pre>\n
To show numbers of bytes instead of number of I\/O requests, employ the\u00a0-b<\/code>\u00a0option.<\/p>\n
$ procinfo -b\r\n<\/pre>\n
Procinfo<\/strong>\u00a0works interactively too, when run fullscreen, this allows you to use the\u00a0d<\/strong>,\u00a0D<\/strong>,\u00a0r<\/strong>\u00a0and\u00a0b<\/strong>\u00a0keys whose functions correspond to their same-named command line flags explained above.<\/p>\n
