.SH NAME
pf \- print process family
.SH SYNOPSIS
.B pf
.I pid
.SH DESCRIPTION
.B pf
prints the ancestor processes of the given process up to the init daemon (or whatever is pid 1 inside a docker container), as well as all its descendents, that is, its child processes and their child processes and so on.
This gives an overview of where that process is coming from, or if it had been disowned, as well as any other processes whose signals it is directly or indirectly waiting for.
It can be useful if an application has become unresponsive or just won't quit. Or just informative about how an application is built and what it is doing.
