    awk 'NF' input.txt
    # 'NF' stand for Number of Fields (this is equivalent to number of columns
    # in a table). If the number of fields is 0 the line must be empty.  In awk
    # 0 is false and non-zero is true. Thus when 'NF' is non-zero (non-empty)
    # it is true, and the line will be printed.
