Question

我正在尝试将两行csv文件合并为一行。

csv文件：

"Operations=5009.0,AverageLatency(us)=714.4248352964663,MinLatency(us)=300.0,MaxLatency(us)=173567.0,95thPercentileLatency(us)=1216.0,99thPercentileLatency(us)=2645.0,Return=5009"
"Operations=4991.0,AverageLatency(us)=831.4189541174113,MinLatency(us)=370.0,MaxLatency(us)=25999.0,95thPercentileLatency(us)=1495.0,99thPercentileLatency(us)=2857.0,Return=4991"

预期产出：

"Operations=5009.0,AverageLatency(us)=714.4248352964663,MinLatency(us)=300.0,MaxLatency(us)=173567.0,95thPercentileLatency(us)=1216.0,99thPercentileLatency(us)=2645.0,Return=5009","Operations=4991.0,AverageLatency(us)=831.4189541174113,MinLatency(us)=370.0,MaxLatency(us)=25999.0,95thPercentileLatency(us)=1495.0,99thPercentileLatency(us)=2857.0,Return=4991"

我试过了：

awk 'NR%2{printf $0" ";next;}1' file.csv

但它不会打印整个第一行。

"Operations=5009.0,AverageLatency(us)=714.4248352964663,MinLatency(us)=300.0,MaxLatency(us)=173567.0,95thPercentileLatency(us)=1216.0,99thPercenti "Operations=4991.0,AverageLatency(us)=831.4189541174113,MinLatency(us)=370.0,MaxLatency(us)=25999.0,95thPercentileLatency(us)=1495.0,99thPercentileLatency(us)=2857.0,Return=4991"

有什么想法吗？

对于您描述的示例，以下代码应该完成这项工作：

awk 'BEGIN{OFS=","}{if(NR%2==1){val=$0;}else{print val,$0}}' inputFile

将奇数行的内容存储在变量中，并将该变量的内容与偶数行中的当前行一起打印。

输出：

"Operations=5009.0,AverageLatency(us)=714.4248352964663,MinLatency(us)=300.0,MaxLatency(us)=173567.0,95thPercentileLatency(us)=1216.0,99thPercentileLatency(us)=2645.0,Return=5009","Operations=4991.0,AverageLatency(us)=831.4189541174113,MinLatency(us)=370.0,MaxLatency(us)=25999.0,95thPercentileLatency(us)=1495.0,99thPercentileLatency(us)=2857.0,Return=4991"

如果输入文件中只有两行，则有一种更复杂的方法可以解决问题（我首先想到的）：

awk 'BEGIN{RS=""; FS="\n"; OFS=",";}{print $1,$2;}' inputFile

此代码将换行符（“\ n”）解释为字段分隔符。也就是说，inputFile中的两行显示为同一数据集的两列。（我们需要RS=""来覆盖其默认值。）
在输出中，此换行符必须替换为逗号（OFS=","）。
