An OS course project for filtering files contents and sorting them ascending/descending by specified field.
First process is a load_balancer which balance sends filenames and filter fields to worker processes and also sends sort field and sort direction to a presenter process. Then worker processes filter files content by inputs and send them to the presenter process. Presenter sorts contents and merges them to last inputs. All interconnections and message passing are using by pipe. (Unnamed pipes between load_balancer and workers , Named pipe between workers and presenter and also between load_balancer and presenter).
In project repository run make command to make project by g++.
After running load_balancer executable file, your commands should be like this :
(<field-name> = <query-value> - )*(<field-to-sort-by> = ascending|descending - )?processes = <number-of-processes> – dir = <relative-dataset-address>
And input files in input directory should be dataset* with contents like this :
