经常使用命令行，比如 curl 测试接口响应时间

for i in {
   
   1..10};do curl -o /dev/null -s   -w "$i | time_namelookup: %{time_namelookup} | time_connect: %{time_connect} | time_starttransfer: %{time_starttransfer} | time_total: %{time_total}\n" "http://httpbin.org/ip";done

1 | time_namelookup: 0.016000 | time_connect: 0.016000 | time_starttransfer: 0.125000 | time_total: 0.141000
2 | time_namelookup: 0.016000 | time_connect: 0.016000 | time_starttransfer: 0.094000 | time_total: 0.109000
3 | time_namelookup: 0.016000 | time_connect: 0.031000 | time_starttransfer: 0.109000 | time_total: 0.109000
4 | time_namelookup: 0.015000 | time_connect: 0.031000 | time_starttransfer: 0.109000 | time_total: 0.109000
5 | time_namelookup: 0.031000 | time_connect: 0.031000 | time_starttransfer: 0.109000 | time_total: 0.109000
6 | time_namelookup: 0.016000 | time_connect: 0.016000 | time_starttransfer: 0.094000 | time_total: 0.109000
7 | time_namelookup: 0.016000 | time_connect: 0.016000 | time_starttransfer: 0.125000 | time_total: 0.125000
8 | time_namelookup: 0.000001 | time_connect: 0.016000 | time_starttransfer: 0.141000 | time_total: 0.141000
9 | time_namelookup: 0.015000 | time_connect: 0.015000 | time_starttransfer: 0.093000 | time_total: 0.109000
10 | time_namelookup: 0.000001 | time_connect: 0.015000 | time_starttransfer: 0.109000 | time_total: 0.125000

奈何命令行参数太多，记不住怎么办？这时候你需要个男人，它就是 man

man

#man curl 
curl(1)                                      Curl Manual                                     curl(1)
