<code>cat ../texts/file_1.txt | tr " " "\n"</code></p></li>
<li><p>Suppress punctuation.
<code>cat ../texts/file_1.txt | tr " " "\n" | tr -d [:punct:]</code></p></li>
<li><p>Make everything lowercase.
<code>cat ../texts/file_1.txt | tr " " "\n" | tr -d [:punct:] | tr [:upper:] [:lower:]</code></p></li>

<li><p>Repeat steps 1 to 7 with the second text.
<code>cat ../texts/file_2.txt | tr " " "\n" | tr -d [:punct:] | tr [:upper:] [:lower:] | sort | uniq > word_list_2.txt</code></p></li>
<li><p>Compare the words used in both texts (common words are in the middle).
<code>comm word_list.txt word_list_2.txt</code><br />

<li><p>Select an interesting word in the result (with 5 lines before and after).
<code>comm word_list_1.txt word_list_2.txt | grep -C 5 "anyword"</code></p></li>
<li><p>Layout the text in a pdf (play with variable elements !).
<code>comm word_list_1.txt word_list_2.txt | grep -C 5 "anyword" | enscript -B -f 'Helvetica-Bold@18/19' -T 16 -p 'my_pdf.ps'</code></p></li>
<li><p>Convert the postscript file to a pdf file.
