I'm in a directory containing all the SAC yearbooks. How could I count the number of times that a German sentence is followed by a sentence in Italian?

• ggrep -Ph "<s" *.txt|ggrep -P -o -A 1 "de"|ggrep -Pc "it"

• ggrep -Ph "<s" *.txt|ggrep -P -A 1 "de"

• ggrep -Ph "<s" *.txt|ggrep -P -B 1 "it"|ggrep -Pc "de" 

Still in the SAC yearbooks directory: How many different token forms of the lemma “avoir” are in the corpus?

• ggrep -Phi "NN" *.txt|ggrep -Po "\b[^\t]+$"|sort|uniq -c|sort -rn|head -n 3 

• ggrep -Phi "\tNN\t" *.txt|ggrep -Po "\b[^\t]+$"|sort|uniq|wc
