Are $2 and $3 supposed to be filenames or space separated parameter lists?

Here is one bash solution using the -v option of printf:

Code:
#!/bin/bash
function csvdiff {
   if [ "$1" == "-s" ] ; then
      local s_args
      shift

      printf -v s_args "%s%s" \
          "$(printf "%s\n" $1 | sort | tr '\n' ' ' )" \
          "$(printf "%s\n" $2 | sort | tr '\n' ' ' )"
   fi
   echo "${s_args:-$@}"
}

echo unsorted
csvdiff "7 2 1 8 9" "5 1 3 7 4"
echo sorted
csvdiff -s "7 2 1 8 9" "5 1 3 7 4"

output:

Code:
unsorted
7 2 1 8 9 5 1 3 7 4
sorted
1 2 7 8 9 1 3 4 5 7

NAME
echo - echo arguments to standard output SYNOPSIS
/usr/ucb/echo [-n] [argument] DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output. echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi- ronment variables. For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows: o echo your current-working-directory's full pathname o pipe the output through tr to translate the path's embedded slash-characters into space-characters o pipe that output through wc -w for a count of the names in your path. example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w" See tr(1) and wc(1) for their functionality. The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's echo() also understands a as the audible bell character; however, these commands do not have an -n option. OPTIONS
-n Do not add the NEWLINE to the output. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWscpu | +-----------------------------+-----------------------------+ SEE ALSO

The -n option is a transition aid for BSD applications, and may not be supported in future releases. SunOS 5.10 3 Aug 1994 echo(1B)
