二重引用符（ "）が出るまで、3番目のフィールドのcsv行をキャプチャしたいと思います。

私はこれを試しました
sed s'/,/ /g' test | awk '{print $3","$4","$5}' | sed s'/"//g'
,,
net2-thrift-netconf,net.driver.memory
net2-thrift-netconf,net.executor.cores
net2-thrift-netconf,net.executor.instances
net2-thrift-netconf,net.executor.memory
net2-thrift-netconf,net.sql.shuffle.partitions
net2-thrift-netconf,net.dynamicAllocation.enabled
net2-thrift-netconf,net.dynamicAllocation.initialExecutors
net2-thrift-netconf,net.dynamicAllocation.minExecutors
net2-thrift-netconf,net.dynamicAllocation.maxExecutors

しかし、構文に問題があります。なぜなら、この構文は「、、」も印刷し、2番目の構文はエレガントではないからです。
予想出力：
net2-thrift-netconf,net.driver.memory,2
net2-thrift-netconf,net.executor.cores,2
net2-thrift-netconf,net.executor.instances,2
net2-thrift-netconf,net.executor.memory,2
net2-thrift-netconf,net.sql.shuffle.partitions,141
net2-thrift-netconf,net.dynamicAllocation.enabled,true
net2-thrift-netconf,net.dynamicAllocation.initialExecutors,2
net2-thrift-netconf,net.dynamicAllocation.minExecutors,2
net2-thrift-netconf,net.dynamicAllocation.maxExecutors,20

これは単なる問題のようです。引用符を削除し、3 番目のフィールドから行末まで印刷します。
$ tr -d \" < file | cut -d, -f3-
net2-thrift-netconf,net.driver.memory,2
net2-thrift-netconf,net.executor.cores,2
net2-thrift-netconf,net.executor.instances,2
net2-thrift-netconf,net.executor.memory,2
net2-thrift-netconf,net.sql.shuffle.partitions,141
net2-thrift-netconf,net.dynamicAllocation.enabled,true
net2-thrift-netconf,net.dynamicAllocation.initialExecutors,2
net2-thrift-netconf,net.dynamicAllocation.minExecutors,2
net2-thrift-netconf,net.dynamicAllocation.maxExecutors,20
したがって、tr -d \"3番目から最後の区切りフィールドまで引用符を削除して印刷します。cut -d, -f3-,
