Number 12 is gone, because I thought the challenge was lame (and I like
unicode.) 

1) gawk '{ wow[$1] += 1;} END { for (key in wow) print key, wow[key]; }' < $1
2) gawk '{ wow[$1] += 1;} END { for (key in wow) print key, wow[key]; }' < $1
3) gawk '{ wow[$1] += 1;} END { for (key in wow) print key, wow[key]; }' < $1
4) gawk 'BEGIN { RS=""; } { last = $0; } END { print last } ' < $1
5) cat $1 $2 | gawk '{ dict[$1] += 1 } END { for (key in dict) if (dict[key] > 1) print key }' 
6) gawk '{ sum += $0 } END { print sum; }' < $1
7) cat $1 $2 | gawk '{ dict[NR] = $0 } END { while (i++ < NR / 2) print dict[i] "," dict[i + NR / 2]  }'
8) gawk '{ for (i = 1; i <= NF; i++) if (tolower($i) ~ /\ythe\y/) totals++; } END { print totals } ' < $1 
9) gawk '{ if (!longline) { longline = $0 } else { longline = longline "," $0 } } END { print longline }' < $1
10) cat $1 | while read line; do grep -q "^$line\$" $2; [[ $? -eq 1 ]] && echo $line; done
11) gawk 'length > max { max = length } END { print max }' < $1
