Hey everyone! Ever found yourself needing to check your internet speed, but you're stuck in the command line and don't want to fire up a whole browser? Or maybe you're a sysadmin who needs to automate speed tests for multiple servers? Well, you're in luck, because today we're diving deep into PseSpeedtest CLI. This nifty tool lets you run speed tests right from your terminal, making it super convenient for quick checks and automated tasks. Forget those clunky web interfaces; we're going to show you how to harness the power of the command line for all your speed testing needs.

What is PseSpeedtest CLI?

So, what exactly is PseSpeedtest CLI, you ask? Essentially, it's a command-line interface (CLI) version of the popular Speedtest.net service. Instead of clicking around on a website, you type a few commands, and bam! You get your download speed, upload speed, and ping. This is a game-changer for anyone who spends a lot of time in the terminal, like developers, network engineers, or even just tech-savvy users who prefer a keyboard-first approach. The convenience factor alone is huge. Imagine running a script that checks your internet speed every hour and logs the results – totally doable with PseSpeedtest CLI. It’s built to be lightweight and efficient, meaning it won’t bog down your system like a full web browser might. Plus, it’s perfect for remote server management where graphical interfaces aren't always available or practical. We’ll be covering how to install it, the basic commands, and some more advanced usage to get you up and running in no time.

Getting Started: Installation

Alright, let's get this show on the road! The first step to using PseSpeedtest CLI is, of course, installing it. The process is pretty straightforward, and depending on your operating system, it might be even easier than you think. For most Linux and macOS users, the easiest way is usually through a package manager. If you're on Linux, you'll likely be using apt, yum, or dnf. For macOS, brew is your best friend. Let’s break it down. If you’re using a Debian-based system like Ubuntu, you’d typically open your terminal and run sudo apt update && sudo apt install psespeedtest-cli. If you’re on a Fedora or CentOS system, you might use sudo dnf install psespeedtest-cli or sudo yum install psespeedtest-cli. Now, if you're rocking a Mac, you'll want to make sure you have Homebrew installed. If you don't, head over to the Homebrew website and follow their simple installation instructions. Once Homebrew is set up, you can install PseSpeedtest CLI with a quick brew install psespeedtest-cli. For Windows users, it's a little different. You might need to download a pre-compiled binary or use a package manager like Chocolatey. The official PseSpeedtest documentation is the best place to check for the most up-to-date Windows installation instructions, as these can sometimes change. Generally, you'll download the executable, place it in a directory that's in your system's PATH, or run it directly from its location. Once installed, you can verify it by simply typing psespeedtest-cli --version in your terminal. If it shows you a version number, you're golden! We'll assume for the rest of this guide that you've got it successfully installed on your system.

Basic Usage: Running Your First Test

Now that you've got PseSpeedtest CLI installed, let's run your very first internet speed test. It's incredibly simple. Open up your terminal or command prompt and type the following command:

psespeedtest-cli

Hit Enter, and the tool will automatically find the best server near you, run the tests, and display the results. You'll typically see your download speed, upload speed, and ping latency. The output might look something like this:

Retrieving speedtest configuration...
Testing from Your ISP (Your IP Address)...
Retrieving ISp information...
Testing download speed...
Download: 94.56 Mbit/s
Testing upload speed...
Upload: 45.32 Mbit/s
Ping: 15.32 ms

Pretty neat, right? This is the most basic way to use the command, and it's perfect for those quick, everyday checks. The tool intelligently selects a server based on your location to give you the most accurate results. No need to manually pick a server unless you want to. This command is your go-to for a quick sanity check on your internet performance. It’s also great for demonstrating to someone that your internet is slow without having to ask them to open a browser and navigate to a website. Just pull up the terminal, run the command, and show them the numbers. We'll explore some options to customize this further in the next sections, but for now, just remember that a simple psespeedtest-cli is all you need for a standard test.

Specifying a Server: Fine-Tuning Your Tests

While PseSpeedtest CLI is smart enough to pick the best server for you automatically, sometimes you might want to be more specific. Maybe you want to test your connection to a server in a particular city, or you're troubleshooting issues with a specific provider. Fortunately, PseSpeedtest CLI makes it easy to select your own server. You can list available servers by running:

psespeedtest-cli --list

This command will output a long list of servers, usually formatted with an ID, the server name, and its location. It can be a bit overwhelming, but you can filter this list using grep on Linux/macOS. For example, if you want to find servers in New York:

psespeedtest-cli --list | grep "New York"

Once you find a server you like, you can tell PseSpeedtest CLI to use it by specifying its ID with the --server option. Let's say you found a server with the ID 12345. You would run your test like this:

psespeedtest-cli --server 12345

This is super useful for testing latency and speeds to specific regions or data centers, which is crucial for gamers or businesses with international operations. You can also use the server name directly if it's unique enough, like psespeedtest-cli --server "New York" (though using the ID is generally more reliable). Remember, choosing a server that's geographically closer to you will generally yield better ping times, while testing to a more distant server can help you understand your connection's performance over longer distances. This level of control gives you the power to really understand the nuances of your internet connection beyond just a single, automatic test.

Outputting Results: JSON and More

For those of you who are looking to integrate speed test results into scripts or analyze them later, the default text output might not be ideal. Thankfully, PseSpeedtest CLI has fantastic options for different output formats, with JSON being a particularly powerful one. To get your results in JSON format, simply add the --json flag to your command:

psespeedtest-cli --json

This will output all the test results as a structured JSON object, making it incredibly easy for scripts to parse and use the data. You'll get information like download, upload, ping, server details, and more, all neatly organized. It's perfect for logging performance over time or feeding data into a monitoring system. Beyond JSON, PseSpeedtest CLI also offers other useful flags. For instance, you can use --simple for a much cleaner, minimal output if you just need the raw numbers without any extra text. There’s also --csv for Comma Separated Values, which is another great format for spreadsheets and data analysis. And if you want to save your results directly to a file, you can use shell redirection. For example, to save the JSON output to a file named speedtest_results.json:

psespeedtest-cli --json > speedtest_results.json

This capability is what makes PseSpeedtest CLI so valuable for automation. You can easily capture and store performance metrics without manual intervention. Whether you're building a dashboard, running automated quality checks, or just want to keep a historical record of your internet speed, these output options give you the flexibility you need.

Advanced Options: Automation and Scripting

We've covered the basics, but the real magic of PseSpeedtest CLI shines when you start using it for automation and scripting. Imagine setting up a cron job on a server to run a speed test every night and email you the results if they drop below a certain threshold. That’s where the --json output combined with a little scripting comes in handy. You can write a simple shell script that executes psespeedtest-cli --json, parses the JSON output using tools like jq, and then performs actions based on the results. For example, you could check if the download speed is less than a specific value:

SPEED_TEST_OUTPUT=$(psespeedtest-cli --json)
DOWNLOAD_SPEED=$(echo $SPEED_TEST_OUTPUT | jq '.download.bandwidth')

if [ "$DOWNLOAD_SPEED" -lt 50000000 ]; then
  echo "Warning: Low download speed detected! ($DOWNLOAD_SPEED bps)"
  # Add your notification logic here (e.g., send email)
fi

This is just a basic example, but you get the idea. You can also use flags like --no-download, --no-upload, or --no-ping to run only specific parts of the test, which can be useful if you're only interested in latency, for instance. Another useful option for scripting is --bytes. By default, speeds are reported in bits per second (bps). Using --bytes will report speeds in Bytes per second (Bps), which might be more intuitive for some file transfer calculations. If you need to run tests against specific IP addresses or hosts, PseSpeedtest CLI often supports options for that too, allowing for very targeted network diagnostics. The possibilities for automating network monitoring and performance checks are vast with this tool.

Troubleshooting Common Issues

Even with a great tool like PseSpeedtest CLI, you might run into a few hiccups along the way. One common issue is related to server selection. If you're getting consistently poor results or errors, try manually selecting a different server using the --server option. Sometimes the default server might be overloaded or experiencing temporary issues. Another potential problem is firewall or network configuration. Ensure that your firewall isn't blocking the ports used by Speedtest.net (typically TCP ports 80 and 443, but sometimes others depending on the server). If you're on a corporate network, there might be restrictions in place that prevent the speed test from running correctly. Check with your network administrator if you suspect this is the case. Permissions can also be an issue, especially on Linux or macOS. Make sure the user running the command has the necessary read/write permissions in the directory where PseSpeedtest CLI is trying to create temporary files or logs, if applicable. Sometimes, a simple update to the latest version of PseSpeedtest CLI can resolve unexpected bugs. Always check the official repository or documentation for the newest release. If you’re still stuck, the community forums or issue trackers for PseSpeedtest CLI are excellent resources for finding solutions or asking for help. Most users find that specifying a known good server or ensuring their network environment is conducive to external connections solves most problems.
