Make crontab send you HTML emails

How to find the PID of a process using a given port?

Sometimes you have a process you lost the PID, and would like to kill it.

You can use top (or better htop) to search for your process name and press k to kill it. But this isn’t optimal when you aren’t sure of its name. A better alternative is to search by the port opened, for example port 80:

sudo lsof -i :80
