FileParser

Using FileParser

• Arguments required are:

  • Directory of the first text file (ex: /home/user/directory/txtfile.txt)
  • One of the following operations ('p' | 's' | 'm' | 'd')
  • Directory of the second text file
  • Delimiter if any exists (use [-f] followed by first delimiter and [-s] followed by second delimiter)
  • Output Directory (Leave blank to save in the program directory, use [-e] followed by export directory)
  • Separate each argument with a single space
  • ex. ./FileParser <first_file_directory> <operation> <second_file_directory> -f <first_delimiter> -s <second_delimiter> -e <export_directory>

• Output will be in the same file directory as (results.txt)

• In case of different file lengths, arrays are concatenated with either 1s - in case of division and multiplication - or 0s - in case of addition or subtraction-
