 3 | > ping [fping] all cloudflare ips to find the best ip
 4 | 
 5 | ## Usage
 6 | 
 7 | Invoking `cfping.sh -h` prints usage information:
 8 | 
 9 |     $ cfping.sh -h
10 |     $ usage: 
11 |     $      cfping.sh -c [-p 2000] [-s 5] [-g 1] [-m 500]
12 |     $         -c     ping [fping] all cloudflare ips to find the best ip
13 |     $         -p <x> sets the time in milliseconds that fping waits between successive
14 |     $                packets to an individual target (default is 2000, minimum is 10)
15 |     $         -s <x> set the number of request packets to send to each target (default is 5)
16 |     $         -g <x> the minimum amount of time (in milliseconds) between sending a
17 |     $                ping packet to any target (default is 1, minimum is 1)
18 |     $         -l     show cloudflare ip location
19 |     $         -m <x> you may want to use this according to system resources limit 
20 |                      larger number faster result (default is 500)
21 | 
22 |     ---
23 | 
24 |     $     cfping.sh -d [-L https://domain.com/xxx] [-N 100] [-P 10] [-I ip]
25 |     $         -d     speed test (default testing best 100 IPs unless -I used)
26 |     $         -L <x> set the file link to test (default: https://speed.cloudflare.com/__down?bytes=100001000)
27 |     $                the domain of this link must have cname record on cloudflare
28 |     $         -N <x> set the number of IPs to test (default is 100)
29 |     $         -P <x> set the parallel number of speed test (default is 10)
30 |     $         -I <x> specify an ip to test
31 | 
32 |     ---
33 | 
34 |     $     cfping.sh [options] <start> <end>
35 |     $         -n <x> set the number of addresses to print (<end> must not be set)
36 |     $         -f <x> set the format of addresses (hex, dec, or dot)
37 |     $         -i <x> set the increment to 'x'
38 |     $         -h     display this help message and exit
39 |     $         -v     display the version number and exit
40 | 
41 | ## ping cloudflare 所有的 IP 找到最优 IP 并测速
42 | 
43 | ### 使用方法
44 | 
45 | `cfping.sh -c`
46 | 
47 | - 1分钟就可以得到结果
48 | - 所有的 ip 都在 ip_sorted
49 | - 如果要显示 ip 位置, 加参数 `-l`
50 | 
51 | `cfping.sh -d`
52 | 
53 | - 默认测速 100 个 ip
54 | - 如果要自定义测速文件, 加参数 `-L`
55 |   文件链接的域名必须在 cloudflare 有 cname 记录
56 | - 如果测速单个指定 IP, 加参数 `-I`
57 | 
58 | 部分网络无法分配到香港 ip, 建议更换其他网络
59 | 
60 | mac / linux 测试通过
