Your #Linux #internals tip of the day: On Linux, there's a magical directory called /proc. In it, every process get a subdirectory according to its PID. Inside of this /proc/pid (that framework is called procfs) you can find a lot of information about the process, (1/3)
everything from it's memory allocation mapping (/proc/pid/maps) to the command line that executed the process (/proc/pid/cmdline) and more... An interesting file to check there is "status". Status sums up a lot of interesting pieces of information such as the PPID, owner (2/3)
uid/gid and more. If you're new to Linux internals, give yourself a tour of the /proc directory. The full documentation of procfs can be read here:
