Poster à la Sauce Hollandaise

Difficulty: **... Preparing time: 1 hour Cooking time: 2 hours

Ingredients

• 2 texts quite long, likely to have words in common
• some elbow grease
• some Helvetica Bold, or better: a freed equivalent

Utensils

• comm
• tr
• cat
• sort
• uniq
• grep (optional)
• less (optional)
• enscript
• ps2pdf

Steps

1. Go to the project directory. cd my_path/PleaseMakeMeDesign

2. Create a new directory where you will work in. mkdir wip

3. Go to this directory. cd wip

4. Display the content of the first file in the shell. cat ../texts/file_1.txt

5. Put every word on a new line. cat ../texts/file_1.txt | tr " " "\n"

6. Suppress punctuation. cat ../texts/file_1.txt | tr " " "\n" | tr -d [:punct:]

7. Make everything lowercase. cat ../texts/file_1.txt | tr " " "\n" | tr -d [:punct:] | tr [:upper:] [:lower:]

8. Sort by alphabetical order. cat ../texts/file_1.txt | tr " " "\n" | tr -d [:punct:] | tr [:upper:] [:lower:] | sort

9. Removes all duplicate words. cat ../texts/file_1.txt | tr " " "\n" | tr -d [:punct:] | tr [:upper:] [:lower:] | sort | uniq

10. Save the result in a file. cat ../texts/file_1.txt | tr " " "\n" | tr -d [:punct:] | tr [:upper:] [:lower:] | sort | uniq > word_list_1.txt

11. Repeat steps 1 to 7 with the second text. cat ../texts/file_2.txt | tr " " "\n" | tr -d [:punct:] | tr [:upper:] [:lower:] | sort | uniq > word_list_2.txt

12. Compare the words used in both texts (common words are in the middle). comm word_list.txt word_list_2.txt
    Tip: use a pager to be able to scroll up and down. comm word_list_1.txt word_list_2.txt | less

13. Select an interesting word in the result (with 5 lines before and after). comm word_list_1.txt word_list_2.txt | grep -C 5 "anyword"

14. Layout the text in a pdf (play with variable elements !). 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'

15. Convert the postscript file to a pdf file. 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' | ps2pdf my_pdf.ps

Alternative end

1. Layout the text on an A4 with automatic font-size so that it fits the page vertically. (the output file is "my_pdf.pdf") comm word_list_1.txt word_list_2.txt | grep -C 5 "anyword" | ../scripts/./v-justify.sh

2. Convert the postscript file to a pdf file. comm word_list_1.txt word_list_2.txt | grep -C 5 "anyword" | ../scripts/./v-justify.sh | ps2pdf my_pdf.ps

Optional: superpose 2 posters !!!

1. Repeat the previous steps to have another poster.

2. Create a text file listing your pdf files. ls *.pdf > pdf_list.txt

3. Superpose ! podofoimpose pdf_list.txt 2in1poster.pdf superimpose.plan lua

Here you are! You now have a wonderful Dutch style poster!
