この規則によると、5つの値を持つ「csv」行のみをキャプチャしようとします。
"","","","",""
例:
more conf.csv
"linux02","cluster26","api2-thrift-apiconf","api.driver.memory",
"linux02","cluster26","api2-thrift-apiconf","api.executor.cores"
"linux02","cluster26","api.executor.instances","2"
"linux02","cluster26","api2-thrift-apiconf","api.driver.memory","2"
"linux02","cluster26","api2-thrift-apiconf","api.executor.cores","2"
"linux02","cluster26","api2-thrift-apiconf","api.executor.instances","2"
"linux02","cluster26","api2-thrift-apiconf","api.executor.memory","2"
"linux02","cluster26","api2-thrift-apiconf","api.sql.shuffle.partitions","141"
"linux02","cluster26","api2-thrift-apiconf","api.dynamicAllocation.enabled","true"
"linux02","cluster26","api2-thrift-apiconf","api.driver.memory","api2-thrift-apiconf","api.executor.memory"
"linux02","cluster26","api2-thrift-apiconf","api.executor.cores"
"linux02","cluster26","api.executor.instances","2"
予想出力：
"linux02","cluster26","api2-thrift-apiconf","api.driver.memory","2"
"linux02","cluster26","api2-thrift-apiconf","api.executor.cores","2"
"linux02","cluster26","api2-thrift-apiconf","api.executor.instances","2"
"linux02","cluster26","api2-thrift-apiconf","api.executor.memory","2"
"linux02","cluster26","api2-thrift-apiconf","api.sql.shuffle.partitions","141"
"linux02","cluster26","api2-thrift-apiconf","api.dynamicAllocation.enabled","true"

使用：
awk -F "," 'NF==5 {print $0}' conf.csv
5つのフィールドを含む行を印刷します。ただし、この行は次のようになります。
"linux02","cluster26","api2-thrift-apiconf","api.driver.memory",
最後のコンマがなりすまし、エラーが発生します。アッその行に5番目のフィールドがあると信じてください。
