bash - Bash 脚本 Perf Stat 到 CSV

Question

我正在尝试将 PERF 结果保存在 CSV 文件中。我需要这些具有不同线程数的数据：

   345,622,750      cache-misses                                                
    22,368,050      tx-start                                                    
    22,362,278      tx-commit                                                   
         5,772      tx-abort                                                    
            94      tx-conflict                                                 
            59      tx-capacity                                                 

  16.641667950 seconds time elapsed

在这样的表中：

缓存未命中 | 交易开始 | tx 提交 | 发送中止 | 交易冲突 | tx 容量 | 运行

（结果线程=1）

（结果线程=2）

（结果线程=4）

（结果线程=8）

……

Code:
file=/dir/out.csv
i=0
threads=1

while [ $i -le 7 ]; do
perf stat -e cache-misses,tx-start,tx-commit,tx-abort,tx-conflict,tx-capacity ./${benchmark}.rtm -v32-r4096 -n10 -p40 -i2 -e8 -s1 -t$threads &>> ${file}
let threads=threads*2
let i=i+1

done

我得到了我的基准和性能的混合输出，我只需要 csv 文件的性能数据（统计数据和运行时）。
