Gather Linux & macOS system information with

Introduction is a small shell script that collects system information from a Linux or macOS host and displays it in a well formatted manner. The information includes hostname, CPU, memory, uptime, load average, netowork stats, and more. On macOS it even grabs the hardware serial numnber and queries Apple’s support website to check and then display the exact model of Apple hardware on which it is running. This information can easily be put in bug reports, README’s, or other support documents. It’s especially effective when connecting to a server that is unfamiliar and information is needed quickly.


I’m on different servers daily and I want a quick look at what hardware the system has. I can fire off a dozen or so commands and find this information. But decided one night to quickly write a script to do it for me, thus this script was born. It used to live in my scriptlets repo, but I recently moved it to its own repo since I have additional plans. As of today, I have plans to refactor the shell script (it’s a bit dirty) and then rewrite this in Go and possibly Perl or Python. I also plan to add support for other OSes including Solaris, AIX, and HP-UX.


You can find the repo here;

There are only three arguments with which it can be run. First, no arguments at all (the absence of an argument is still an argument, right?). Second, --connections to display currently ESTABLISHED network connections. And finally, --containers, to show running containers (specifically containers running in Docker, though I’d like podman, cri-o, and containerd] containers supported in the future).

To make it easy to run when I am in any enviroment, I’ve created a small url at; which points directly to the raw script in the repository. Which makes it really easy to run;

curl -sSL | sudo bash

NOTE: Obviously I wouldn’t recommend just blindly running the command above if you are concerned about security at all. Download the script, view the source, and if you trust it, use it.

Sample output

Here are some samples of the many times that I have run this script;

While this may not be useful for many people, it is for me. By gathering a little information up front you can easily save yourself some time later on by not hunting down system information one command at a time, especially in troubleshooting or to include in bug reports.
