There are lots of online tools for checking your ISP provided internet speed. Most are web based interfaces and there are some great ones out there. The most popular is probably www.speedtest.net, but we also have www.fast.com, www.speedof.me, … even Google let’s you do it directly from its search page (you have to search using US-based google.com, not any of Google’s other country TLDs).
You can also do it from the Linux command line using a few open source tools. Here is how to do it…
(Note that all my speeds are low here since I’m downloading in the background!)
Speedtest.net
You can download the python script to run the speedtest.net Linux command line interface tool from here (obviously python is a pre-requisite):
https://github.com/sivel/speedtest-cli
You can install using git, pip/easy-install or download with wget. I’m going to use pip
pip install speedtest-cli
Typing speedtest-cli –help shows you this output listing all available options:
usage: speedtest-cli [-h] [--bytes] [--share] [--simple] [--list] [--server SERVER] [--mini MINI] [--source SOURCE] [--timeout TIMEOUT] [--secure] [--version] Command line interface for testing internet bandwidth using speedtest.net. -------------------------------------------------------------------------- https://github.com/sivel/speedtest-cli optional arguments: -h, --help show this help message and exit --bytes Display values in bytes instead of bits. Does not affect the image generated by --share --share Generate and provide a URL to the speedtest.net share results image --simple Suppress verbose output, only show basic information --list Display a list of speedtest.net servers sorted by distance --server SERVER Specify a server ID to test against --mini MINI URL of the Speedtest Mini server --source SOURCE Source IP address to bind to --timeout TIMEOUT HTTP timeout in seconds. Default 10 --secure Use HTTPS instead of HTTP when communicating with speedtest.net operated servers --version Show the version number and exit
I’ve found the best way to run this is to use the bytes option, and pick a server relatively local (you can find the available servers by running speedtest-cli –list , probably worth grepping to narrow it down to your country, speedtest-cli –list | grep “Great Britain” ):
speedtest-cli --bytes --server 3730
Returns:
Retrieving speedtest.net configuration... Retrieving speedtest.net server list... Testing from Moldtelecom (93.115.84.202)... Hosted by Virgin Media (Edinburgh) [532.85 km]: 170.272 ms Testing download speed........................................ Download: 1.92 Mbyte/s Testing upload speed.................................................. Upload: 0.95 Mbyte/s
And comparing to the web interface we see:
Remember 1 megabyte per second = 8 megabits per second, and the web interface returns results in megabits per second.
speedtest.sh
If you don’t have python installed you can use the script below which is entirely written in bash. This could be useful for running on some internet-of-things devices which have telnet or SSH but don’t have python installed. Or to run on some routers (e.g. DD-WRT or Tomato) which you can SSH into but may not have python installed.
Download from http://dl.getipaddr.net/ or just run these commands to download and run once you’re in the folder you want to keep the script in:
wget https://raw.github.com/blackdotsh/curl-speedtest/master/speedtest.sh && chmod u+x speedtest.sh bash speedtest.sh
Returns:
-------------Speed test-------------------- Testing North America locations Speedtest from Portland, Oregon, USA [ generously donated by http://bonevm.com ] on a shared 100 Mbps port Download Speed: .33 MB/sec Upload speed: .62 MB/sec Speedtest from Seattle, Washington, USA [ generously donated by http://ramnode.com ] on on a shared 1 Gbps port Download Speed: 1.22 MB/sec Upload speed: .95 MB/sec
This script will keep looping through different servers until you cancel it (Ctrl+C), at least I’ve never been patient enough to let it go long enough to finish on its own!
I’ve found that speedtest.sh tends to show much lower speeds than the other tools.
netspeed.sh
[Note netspeed.sh has now been depreciated (the author commented on this post below). You can find his new improved tool at https://git.io/speed instead.]
Or download and run with:
wget https://gist.githubusercontent.com/rsvp/1272488/raw/bf7ff5ed508b88c7e2030ea891b154c08f0690b5/netspeed.sh && chmod u+x netspeed.sh bash netspeed.sh
Returns:

Hi ! from the guy who wrote netspeed.sh …
# SUMMARY
The gist above, *netspeed.sh*, has been deprecated.
## Good news
Work has shifted to using the infrastructure of speedtest.net and fast.com —
again made easily accessible by **Bash shell scripts** for all POSIX and Linux systems.
Please visit https://git.io/speed to obtain the code. PR are welcomed!
