pwordcount

• Synopsis:
  bash ./pwordcount [-h|help] [-m t|u|o] [-p n] files...

• Description:
  pwordcount is a command-line program that performs word counting tasks on text files using multiprocessing. It supports three modes of operation: counting total words, counting unique words, and counting occurrences of each unique word. The program can divide the counting operations across multiple processes to handle a single file or multiple files efficiently.

• Arguments:

  • m: option that defines the counting mode (only one mode per execution)
    • t: counts the total words (default option)
    • u: counts the total number of unique/different words
    • o: counts the number of occurrences of each word in the input files
      
  • p: option that defines the parallelization level
    • n: defines the number of allowed child processes (by default n=1)
    • h | help: shows help information

• Example usage:

  • ./pwordcount -m t file1.txt
  • ./pwordcount -p 2 -m u file2.txt
  • ./pwordcount -m o -p 4 file2.txt file3.txt
  • ./pwordcount -p 5 file2.txt
  • ./pwordcount -m u file3.txt
  • ./pwordcount file1.txt
  • ./pwordcount file2.txt file3.txt file4.txt
  • ./pwordcount -m t -p 1 file1.txt file2.txt file3.txt
  • ./pwordcount -m o -p 4 file1.txt file2.txt. file3.txt file4.txt
  • ./pwordcount help
