This should be simple, but I'm just not seeing it.
If I have a process ID, how can I use that to grab info about the process such as the process name.

In this quick article, we've explored how to get the name and the command line of a given PID in the Linux command line. The ps -p <PID> command is pretty straightforward to get the process information of a PID. Alternatively, we can also access the special /proc/PID directory to retrieve process information.
Task Manager can be opened in a number of ways, but the simplest is to select Ctrl+Alt+Delete, and then select Task Manager. In Windows, first click More details to expand the information displayed. From the Processes tab, select Details to see the process ID listed in the PID column. Click on any column name to sort.
If you want to see the path of the process by PID. You can use the pwdx command. The pwdx command reports the full path of the PID process.
The process identifier (process ID or PID) is a number used by Linux or Unix operating system kernels. It is used to identify an active process uniquely.
Under Linux, you can read proc filesystem. File /proc/<pid>/cmdline contains the commandline.
