Shell Version #1

Comments on this implementation:
  • uses tr to split input stream into "words" (space-separated)
  • stores prefixes and suffixes in a file called suffixes of the form 

       prefixWord1 prefixWord2 suffixWord
   ...

  • this file is built by simply appending 3-word phrases
  • thus, prefixes may be repeated throughout the file
  • uses grep to do the lookup work   (find all lines for given prefix)
  • uses `..` and sed to combine suffixes into list of words
  • uses shift to choose a random element from this list
