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

    if(document.createRange)//Firefox, Chrome, Opera, Safari, IE 9+
    {
        range = document.createRange();//Create a range (a range is a like the selection but invisible)
        range.selectNodeContents(contentEditableElement);//Select the entire contents of the element with the range
        range.collapse(false);//collapse the range to the end point. false means collapse to end rather than the start
        selection = window.getSelection();//get the selection object (allows you to change selection)
        selection.removeAllRanges();//remove any selections already made
