How to use the command fast (with examples)
Fast is a command-line tool that allows users to test their internet download and upload speed. It provides quick and accurate speed measurements and is simple to use. In this article, we will explore three different use cases of the fast command, including measuring the current download speed, measuring the current upload speed, and displaying the results on a single line to reduce spacing.
Use case 1: Measure the current download speed
Code:
fast
Motivation: This use case is helpful for users who want to know the speed at which their internet is currently downloading data. It can be useful to troubleshoot slow connections, monitor performance, or simply to satisfy curiosity.
Explanation: The above command fast alone without any additional arguments will measure the current download speed. It will connect to a server and perform a speed test to calculate the download speed.
Example output:
Download speed: 50.22 Mbps
In this example, the command returns a download speed of 50.22 Mbps. The output may vary depending on your internet speed.
Use case 2: Measure the current upload speed in addition to download speed
Code:
fast --upload
Motivation: This use case is ideal for users who want to measure both their download and upload speeds. It allows them to assess their overall internet performance and determine whether both download and upload speeds are satisfactory for their needs.
Explanation: Adding the --upload flag to the command fast will measure both the download and upload speeds. The command will connect to a server, conduct a speed test, and provide the results for both download and upload speeds.
Example output:
Download speed: 50.22 Mbps
Upload speed: 20.12 Mbps
In this example, the command returns a download speed of 50.22 Mbps and an upload speed of 20.12 Mbps. The output may vary depending on your internet speed.
Use case 3: Display results on a single line to reduce spacing
Code:
fast --single-line
Motivation: This use case is beneficial for users who prefer a more concise output with reduced spacing. It can be useful when scripting or logging speed tests, as it provides a compact and streamlined view of the results.
Explanation: By adding the --single-line flag to the fast command, the results will be displayed on a single line, reducing spacing between the test results.
Example output:
Download speed: 50.22 Mbps - Upload speed: 20.12 Mbps
In this example, the command returns the download speed and upload speed on a single line. The output may vary depending on your internet speed.
Conclusion:
The fast command is a versatile tool for measuring internet download and upload speeds. It allows users to quickly assess their current internet performance, troubleshoot connectivity issues, and monitor their network speed. By understanding and utilizing the different use cases of the fast command, users can gather valuable information about their internet speed and make informed decisions based on their needs and preferences.
