Parsing a CSV file using gawk

Question

How do you parse a CSV file using gawk? Simply setting FS=\",\" is not enough, as a quoted field with a comma inside will be treated as multiple fields.

Answer 1

The gawk version 4 manual says to use FPAT = "([^,]*)|(\"[^\"]+\")"

When FPAT is defined, it disables FS and specifies fields by content instead of by separator.
