curl - 使用 curl 命令将时间戳和延迟输出到文件

Question

我正在使用该curl命令来测量日期/时间（或时间戳）以及请求的延迟。这里执行相同的命令，1000次对系统进行压力测试，我的代码如下：

curl -s -v -i -I http://172.16.20.8:8000/files_to_curl/vid.mp4?[1-1000] | grep "Date:","%{http_code},%{time_namelookup},%{time_connect},%{time_appconnect},%{time_pretransfer},%{time_redirect},%{time_starttransfer},%{time_total},%{size_download},%{speed_download}\n" >> test_time.txt

我的问题是我一次只能保存一个信息，如果保存了日期，则延迟不能，反之亦然。我是 shell 命令的新手，所以请告诉我哪里做错了。

Thanks, Maxim I have also worked out a way which can be helpful.

From this answer on timestamp ts, I tried this and it works well:

curl -s -v -i -I http://xxx.xx.xx.x:8000/files_to_curl/vid.mp4?[1-1000] -o /dev/null -w ",%{http_code},%{time_namelookup},%{time_connect},%{time_appconnect},%{time_pretransfer},%{time_redirect},%{time_starttransfer},%{time_total},%{size_download},%{speed_download} \n" | ts '[%Y-%m-%d %H:%M:%S]' >> test_file.txt
