This is a simple exercise that demands to create a Bash script that provides statistics on the use of characters in a language.

NB: The French language is chosen.

Therefore, a dico.txt file is provided. This file contains all French words, one word per line, totally with uppercase characters:

ABAISSA
ABAISSABLE
ABAISSABLES
ABAISSAI
ABAISSAIENT
[...]

• The first mission is to extract the number of words using each letter of alphabet. The script will take as parameter the name of the dictionary file (dico.txt).
• The second mission is to create additional functionnality for your script. This feature can be activated by the presence of a second parameter of your own choice.

No requirements for Linux users.

For Windows users:

• Vagrant
• VirtualBox

It is recommended that Windows users use the Git Bash terminal

For Windows users:

1. Download an install Vagrant and VirtualBox.

2. Clone the repository or download it.

3. Open your Git Bash terminal to the project folder.

4. Run vagrant up to install the linux OS.

5. Then run vagrant ssh.

6. Then change directory to access your shared files by running cd /vagrant.

7. Finally run the following command:

   ./langstat.sh dico.txt

For Linux users:

1. Clone the repository or download it.

2. Run the following command:

   ./langstat.sh dico.txt

The output sould be like:

278814 - E
229938 - A
219131 - I
210391 - R
207889 - S
179165 - N
176030 - T
158282 - O
    [...]

To achieve the second mission, you can insert a second parameter when running the script:

• To display result in ascending order, type:

  ./langstat.sh dico.txt --ascending

  Output:

   529 - W
   1595 - K
   5743 - J
   8262 - X
   11030 - Y
   16340 - Q
   30562 - V
   34982 - Z
     [...]

• To sort result by characters, type:

  ./langstat.sh dico.txt --char

  Output:

   229938 - A
   43471 - B
   98832 - C
   72481 - D
   278814 - E
   36777 - F
   48942 - G
   35940 - H
     [...]

• To sort result by characters in reversed way, type:

  ./langstat.sh dico.txt --rchar

  Output:

  Z - 34982
  Y - 11030
  X - 8262
  W - 529
  V - 30562
  U - 108195
  T - 176030
  [...]

• To display result with some infos such as execution duration, script's name, shell type, current script path and script's user, type:

  ./langstat.sh dico.txt --infos

  Output:

  278814 - E
  229938 - A
  219131 - I
  210391 - R
  207889 - S
  179165 - N
  176030 - T
  158282 - O
      [...]
