You are welcome, of course.

Also, you might want to take a closer look at fuser, since it has some
other nifty uses. Many of which people usually resort to lsof for, like
discovering which process is using a given tcp/udp port.

fuser -n tcp <port_number>

I actually find myself using fuser at least once or twice a day. Not
to mention the huge number of scripts I have that use them, mostly to
see if a given file is in use. And yes, I'm awake that kind of use is
prone to race conditions if overused :)
