This project is divided into 3 modules. The main file is 537ps. It reads options from command line and determines the value of flags to enable or disable options. Each flag is used to control the display of specific information. If there is a pid input, then use function printflag to print the information of this pid. If there is no pid input from command line, then it will get current uid number to call function getlist to get all the possible pid numbers. Then print the required information for every pid of this uid.

The getlist file includes the function that can return all the possible pids that matching the input uid.

The parser file includes the function that can return specific information of the pid for each option.
