See if the following bash script works. It works fine here. If $RANDOM function causes error because not bash, there are other ways to generate random numbers under Unix.
Code:
# usage: temp.sh iterations sample_size seed

iterations=${1:-10} sample_size=${2:-3} # RANDOM=$3

seq_cnt=`cat Infile1 | wc -l`
if [ $sample_size -gt $seq_cnt ]; then echo ss too big!!; exit; fi

iteration=1
while [ $iteration -le $iterations ]; do
  rm -f prev_used_nums.txt unsorted-1.txt unsorted-2.txt
  touch prev_used_nums.txt
  seqs_written=0
  while [ $seqs_written -lt $sample_size ]; do
    let "num_to_use = 1 + ($RANDOM % seq_cnt)"
    grep -q $num_to_use prev_used_nums.txt
    if [ $? -eq 0 ]; then continue; fi # already used $num_to_use
    sed -n "$num_to_use { p; q }" Infile1 >> unsorted-1.txt
    sed -n "$num_to_use { p; q }" Infile2 >> unsorted-2.txt
    echo $num_to_use >> prev_used_nums.txt
    let "seqs_written++"
  done
  sort unsorted-1.txt > OutFile1-$iteration
  sort unsorted-2.txt > OutFile2-$iteration
  let "iteration++"
done

NAME
pescetti -- Pseudo-Duplimate Generator SYNOPSIS
pescetti DESCRIPTION
This manual page documents briefly the pescetti command. OPTIONS
Here are a list of the available options and what they do. You must specify exactly one from --demo, --generate or --load. --help Prints the help text --demo Demonstration mode. Generates one hand with permutations and the tutorial for how to use them. --generate=N Generate N random boards --load=boards.txt Load boards+analysis from boards.txt --load-dds=boards.dds Load boards from boards.dds in dds format --load-analysis=tricks.txt Load analysis from tricks.txt --permutations=permutations.txt Generate the permutations and save them to the given file --curtains=curtains.txt Save curtain cards to file curtains.txt --save=boards.txt Save the boards+analysis to boards.txt --save-dds=boards.dds Save the boards to boards.dds in dds format --save-analysis=tricks.txt Save the analysis to tricks.txt --format=html|txt|pdf Set the output mode to the given format --title=title Set the title for the output --output=hands.txt Print the hands to hands.txt, rather than to standard output --stats Generate statistics about the set of boards; included in the hands output --analyze Run the dds analyzer on the boards and print the resulting numberof tricks (warning SLOW) --criteria= A list of criteria to apply to each generated hand to generate specific hand types. The list should be space separated and each item may be suffixed with a colon and a (fractional) probability value which can be used to weight the criteria. E.g. --criteria="weaknt:0.8 strongnt:0.5" Valid criteria are: unbalanced weaknt strongnt twont strongtwo weaktwo three twoclubs 4441 singlesuit twosuits partscore game slam game-invite slam-invite jumpshift jumpfit splinter bacon weird --probability=factor Generate hands matching the criteria with only the given probability. Factor is in the range 0 to 1. On each attempt to generate a board it is rejected if it doesn't match the criteria with the given probability. A factor of about 0.8 gives roughly half matching boards AUTHOR
