用行号ping

Question

简单的问题：如何ping在 Linux 上显示输出中的行号？

我的意思是：

1 64 bytes from www.site.com (2.7.1.1): icmp_req=1 ttl=247 time=17.9 ms
2 64 bytes from www.site.com (2.7.1.1): icmp_req=2 ttl=247 time=16.1 ms
3 64 bytes from www.site.com (2.7.1.1): icmp_req=3 ttl=247 time=16.1 ms

Answer 1

该nl命令将行号添加到其输入中，因此您可以将输出通过管道ping传输到nl。

% ping -c3 google.com | nl
     1  PING google.com (74.125.224.105) 56(84) bytes of data.
     2  64 bytes from nuq04s08-in-f9.1e100.net (74.125.224.105): icmp_req=1 ttl=55 time=31.2 ms
