topmostp
topmostp (Topmost Ports) is a tool that allows you to quickly retrieve the most used ports. The source of the ranking is the nmap-services in the nmap repo.
At SecSI we found it useful to get this information to use it in a pipeline of scripts.
You can easily install it by running:
pip install topmostp
topmostp --help
This will display help for the tool. Here are all the commands it supports.

A pratical example is the following:
naabu -p $(topmostp top 15 -s) -host secsi.io
In this snippet the output of topmostp is used to retrieve the list of the top 15 ports and it is chained with the naabu port scanning tool.
