+# TODO: Modify this file to create a shell script that is able to use awk to go through a file formatted like 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 POKEMON.DAT ======
+#    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 pokemon.dat. However, you can assume that any file passed to this script will be formatted exactly the way pokemon.dat is formatted.
