Write a utility program, ModifyAndCopyRxLogs: Usage: ModifyAndCopyRxLog -i <filepath> -o <output_directory> [-c <1,2,3,4,...>] [-p prefix] [-t] -i Input filepath -o Output directory (can be a network share) -c Specifies the columns to be included (all other columns are deleted from the file) -p Specifies an optional prefix to be added to the filename -t If specifies appens date and time (e.g., _2017_5_23__21_20) to the end of the filename Description: RxLogs are pipe(|)-delimited files (similar to CSV). ModifyAndCopyRxLogs reads the file specified by log_filepath and makes the following changes: 1. Deletes all columns not specified with the -c command-line parameter 2. Escapes all double-quotes (e.g., " -> "") 3. Escapes all commas (any field containing a comma is surrounded by double-quotes. e.g., |hello,world| -> |"hello,world"|) 4. Changes all pipe (|) characters to commas (,) 5. Publishes the file to output_directory while adding the "prefix" if one is specified on the command-line, and adding date and time (e.g., _2017_5_23__21_20) to the end of the filename if -t is specified Return Value: 0 Successfully processed the file 1 Input file not found 2 Cannot copy to output directory
