Ok. I'm just gonna lay it out there for ya. I'm not the best coder (obviously but here is what I have. Code is below.

Code:
#!/bin/sh
n=$(cat $fipslist | wc -l)
i=1
for ((i; i<n+1; i++))
do
  fipscode=$(cat $fipslist | head -$i | tail -1 | cut -c 17-21)
  countyname=$( cat $fipslist | grep $fipscode | cut -c 1-16 | tr -d " ")
  fipschecker=$(cat $cancountieslist | grep $fipscode" ")

  if [ "$fipschecker" != "" ]; then
    #echo $fipscode","$countyname","$threatcodecan >> $wcnoutput
    #HERE IS WHERE I NEED YOUR CODE.  RIGHT NOW IT JUST OVERWRITES $WCNOUTPUT.  BASED ON THE CONDITION ABOVE IN THE IF   STATEMENT, IF TRUE, I NEED IT TO JUST OPEN $WCNOUPUT, AND APPEND $THREATCODECAN (WHICH I HAVE ASSIGNED ELSEWHERE) TO $WCNOUTPUT IN THE THIRD COLUMN OF THE FILE (WHICH IS A CSV FILE).  LEAVING ALL OTHER LINES IN $WCNOUTPUT UNCHANGED.
  fi
done

RAKE(1) 						 Ruby Programmers Reference Guide						   RAKE(1)

NAME
rake -- Ruby Make SYNOPSIS
rake [--f Rakefile] [--version] [-CGNPgnqstv] [-D [PATTERN]] [-E CODE] [-I LIBDIR] [-R RAKELIBDIR] [-T [PATTERN]] [-e CODE] [-p CODE] [-r MODULE] [--rules] [variable=value] target ... DESCRIPTION
Rake is a simple ruby(1) build program with capabilities similar to the regular make(1) command. Rake has the following features: o Rakefiles (Rake's version of Makefiles) are completely defined in standard Ruby syntax. No XML files to edit. No quirky Makefile syntax to worry about (is that a tab or a space?). o Users can specify tasks with prerequisites. o Rake supports rule patterns to synthesize implicit tasks. o Flexible FileLists that act like arrays but know about manipulating file names and paths. o A library of prepackaged tasks to make building rakefiles easier. OPTIONS
--version Display the program version. -C --classic-namespace Put Task and FileTask in the top level namespace -D [PATTERN] --describe [PATTERN] Describe the tasks (matching optional PATTERN), then exit. -E CODE --execute-continue CODE Execute some Ruby code, then continue with normal task processing. -G --no-system --nosystem Use standard project Rakefile search paths, ignore system wide rakefiles. -I LIBDIR --libdir LIBDIR Include LIBDIR in the search path for required modules. -N --no-search --nosearch Do not search parent directories for the Rakefile. -P --prereqs Display the tasks and dependencies, then exit. -R RAKELIBDIR --rakelib RAKELIBDIR --rakelibdir RAKELIBDIR Auto-import any .rake files in RAKELIBDIR. (default is rakelib ) -T [PATTERN] --tasks [PATTERN] Display the tasks (matching optional PATTERN) with descriptions, then exit. -e CODE --execute CODE Execute some Ruby code and exit. -f FILE --rakefile FILE Use FILE as the rakefile. -h --help Prints a summary of options. -g --system Using system wide (global) rakefiles (usually ~/.rake/*.rake ). -n --dry-run Do a dry run without executing actions. -p CODE --execute-print CODE Execute some Ruby code, print the result, then exit. -q --quiet Do not log messages to standard output. -r MODULE --require MODULE Require MODULE before executing rakefile. -s --silent Like --quiet, but also suppresses the 'in directory' announcement. -t --trace Turn on invoke/execute tracing, enable full backtrace. -v --verbose Log message to standard output (default). --rules Trace the rules resolution.
