+# 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):
+
+# initialize variables
+double countNames
+double countHP
+double total
+double avgHP
+double avgAttack
+
+# increment counter for each name in file to find line count
+function countlines(sumTotal){
+        # Increment countNames by 1
+        countNames++
+        }
+# run countlines to find total number of lines
+{countlines($0)}
+
+# Calculate mean given column as a parameter
+function mean(column){
+        # Increment countMean variable by 1
+        countMean++

+# ===== SUMMARY OF DATA FILE =====
+#    File name: [VALUE]
+# Display file name
+{print "File name: " FILENAME }
+#    Total Pokemon: [VALUE]
+# Display total count of pokemon
+{print "Total Pokemon: " countNames }
+#    Avg. HP: [VALUE]
+# Display Average HP of all pokemon
+{avgHP=mean($5)}
+{print "Avg. HP: " total/countMean }
+#    Avg. Attack: [VALUE]
+# Display Average Attack of all pokemon
+{avgAttack=mean($6)}
+{print "Avg. Attack: " total/countMean}
+# ===== 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.
