This shard is only an experiment to use the raw socket in the Crystal language.

## Installation

1. Add the dependency to your `shard.yml`:

```yaml

dependencies:

  ping:

    github: arcage/ping.cr

```

2. Run `shards install`

require "ping"

Ping.command(ARGV.shift)

```

```shell

$ sudo crystal src/ping_command.cr 192.0.2.1

PING 192.0.2.1: 56 data bytes

64 bytes from 192.0.2.1: icmp_seq=0 ttl=253 time=1.903 ms

64 bytes from 192.0.2.1: icmp_seq=1 ttl=253 time=1.466 ms

64 bytes from 192.0.2.1: icmp_seq=2 ttl=253 time=1.355 ms

--- 192.0.2.1 ping statistics ---

5 packets transmitted, 5 packets received, 0% packet loss

round-trip min/avg/max/stddev = 1.355/1.783/2.115/0.346 ms
