To compile this code, simply run "make" within the code directory.

To run the code, simply run "./PMan" (after compiling) within the code directory.

PMan is a basic process management tool. Its commands are:

bg [executable] [arguments]

Begins a process on the program specified by "executable", with the

desired "arguments". This accepts either a path to an executable or a

executable in the environment path.

bglist

Lists all the processes currently managed by PMan.

bgkill [pid]

Kills the process with process ID "pid", if it was started by PMan. After

it is killed, the process is no longer managed by PMan.

bgstop [pid]

Kills the process with process ID "pid", if it was started by PMan and

is currently running. It can be restarted with bgstart.

bgstart [pid]

Starts the process with process ID "pid", if it was started by PMan and

is currently stopped.

pstat [pid]

Displays various information about the process.

When a process managed by PMan terminates, it will be cleaned up and the user will

be notified that the process terminated. This may not occur until the next command is

entered by the user, since the main program is blocked as it waits for user input.
