-# TODO: Modify this file to create a shell script that is able to use awk to go through a file formatted like best_pokemon.dat and provides a printed report in the following format (where your script correctly calculates the values that go into the [VALUE] placeholders):
-# ===== SUMMARY OF DATA FILE =====
-#    File name: [VALUE]
-#    Total Pokemon: [VALUE]
-#    Avg. HP: [VALUE]
-#    Avg. Attack: [VALUE]
-# ===== END SUMMARY =====
-
-# The "Avg." values should be calculated as mean values for the corresponding columns.
-# The spacing and header formatting should match the above formatting description exactly.
-# There should be a comment explaining the purpose of each line in your shell script. 
-# The data file will be passed in to the script as a positional parameter and will not necessarily be called best_pokemon.dat. However, you can assume that any file passed to this script will be formatted exactly the way best_pokemon.dat is formatted.
