$ curl -L -o fast


$ wget -O fast

Once insallation is complete:

chmod +x fast

Test command:



Since it isn’t a hidden file, I create a hidden folder in my home directory called .fast, then place the executable fast file in there.

Next, create a bash alias:

alias st="/home/keith/.fast/fast"

  • For this alias, I chose “st” to represent “speed test”


That’s all.
