Awk print rows that aren't blank in specific field

# Basic syntax:
awk -F'delimiter' '$column# != ""' input_file

# Example usage:
awk -F'\t' '$3 != ""' input_file
# This prints every line in which the 3rd tab-delimited column is 
# not blank. Change the 3 to any column and/or add other conditions 
# for your application
