Use this to adjust the URLs of links within Classic Salesforce Knowledge 
Articles to reference the destination Salesforce instance instead of the
source instance.

Usage: $0 input-file.csv prefix
  where
    input-file.csv is an extract of Classic Knowledge Articles from
        Salesforce in the form of "Id","Article_content"
    prefix is a string to prepend to the final output file name.
        If none is provided then this will be 'Replaced_'
Script will
  remove all line breaks (collapsing into a single line, outputting
    intermediate temp file chomped.csv)
  introduce line breaks ahead of head article Id (making the CSV one article 
    per line, outputting intermediate temp file one-per-line.csv)
  replace all instances of /Knowledge_Article_Type/ with /Article/, writing
    the final output to a new file entitled as Replaced-input-file.csv (the
    input file name prefixed with 'Replaced-', or with the prefix text if
    provided.)
