如何从第三个字段打印 CSV

Question

我想从第三个字段中捕获 csv 行，直到和没有双引号 (")

more test

"linux02","PLD26","net2-thrift-netconf","net.driver.memory","2"
"linux02","PLD26","net2-thrift-netconf","net.executor.cores","2"
"linux02","PLD26","net2-thrift-netconf","net.executor.instances","2"
"linux02","PLD26","net2-thrift-netconf","net.executor.memory","2"
"linux02","PLD26","net2-thrift-netconf","net.sql.shuffle.partitions","141"
"linux02","PLD26","net2-thrift-netconf","net.dynamicAllocation.enabled","true"
"linux02","PLD26","net2-thrift-netconf","net.dynamicAllocation.initialExecutors","2"
"linux02","PLD26","net2-thrift-netconf","net.dynamicAllocation.minExecutors","2"
"linux02","PLD26","net2-thrift-netconf","net.dynamicAllocation.maxExecutors","20"

我试过这个

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
,,

但是我的语法有问题，因为这种语法也打印“,,”，而第二种语法并不优雅。

预期输出：

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

Answer 1

看起来这只是一个问题，或者删除引号然后从第三个字段打印到行尾：

$ 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

所以从第三个到最后一个分隔的字段中tr -d \"删除引号和cut -d, -f3-打印,。
