Skip records containing no field separator in awk

Question

In awk, I am using / as the field separator. However,there are some records in the input file that do not contain this field separator. How does awk behave for such records? Is there any way to tell awk to skip such records?

If there's no field separator on a line, then the line consists of a single field.

If you want to skip lines with a single field, you can start your awk program with

NF == 1 {next}
