摆脱最后一个（\ n）符号

Question

我正在尝试解析一个csv文件，其中输入用'“'括起来，并用逗号'，'分隔，并显示以下代码：

split($0,data,",")
print "\""data[1]"\",\""data[7]"\",\""data[2]

它应该分开列，如果需要的话执行操作，所以不建议按原样打印;） 所以问题是最后一列-它用'\ n'符号抓住，所以下一列覆盖了我当前的行，即初始文件：

"00:00:00","87100","2381","",""," ","13"
"00:00:01","56270","0098","",""," ","37"
"00:00:01","86917","0942","",""," ","12"

所以代替这个：

 "00:00:00","13","87100"
 "00:00:01","37","56270"
 "00:00:01","12","86917"

我得到这个：

","87100"
","87100"
","87100"

（“ data [1]”，“ data [3）被覆盖。我已经从打印列表中删除了最后一列，并且工作正常。而且，我不能在最后一列之后添加逗号太多。还有其他代码建议吗？

Answer 1

而不是分割每一行，您应该将字段分隔符指定为'，'（使用-F）。然后，打印每个字段要简单得多（仍附上引号）。您仍然可以以$ 0的价格访问整行。

object(A)#1 (1) { ["b":"A":private]=> object(B)#2 (1) { ["a":"B":private]=> *RECURSION* } } 

object(B)#2 (1) { ["a":"B":private]=> object(A)#1 (1) { ["b":"A":private]=> *RECURSION* } }
