Thanks guys,

Not sure if it's the best solution, but in the end I chose to create another nested function to run the awk command:

Code:
function csvdiff() {
  function _csvdiff() {
    awk '
      ...
      }' OFS="\t" $@
  }
  
  if [ "$1" == "-s" ] ; then
    _csvdiff <(sort "$2") <(sort "$3")
  else
    _csvdiff $@
  fi
  
  unset -f _csvdiff
}

This seems to work fine. Thanks for the input though! Both solutions would have worked, although I'm reading in files and not space separated lists.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
