Assuming that check.sh contains:
Code:
nawk '/^#/ {next} NR==FNR {prod[$0]=$0;next} {if ($0 in prod) { delete prod[$0] } else {print }}; END {for (i in prod) print prod[i]}' prod.properties back.properties

change it to:
Code:
file1="$1"
file2="$2"
nawk '/^#/ {next} NR==FNR {prod[$0]=$0;next} {if ($0 in prod) { delete prod[$0] } else {print }}; END {for (i in prod) print prod[i]}' "$file1" "$file2"

or just:
Code:
nawk '/^#/ {next} NR==FNR {prod[$0]=$0;next} {if ($0 in prod) { delete prod[$0] } else {print }}; END {for (i in prod) print prod[i]}' "$1" "$2"

or even:
Code:
nawk '/^#/ {next} NR==FNR {prod[$0]=$0;next} {if ($0 in prod) { delete prod[$0] } else {print }}; END {for (i in prod) print prod[i]}' "$@"
