{{lowercase}}
<code>[[wikipedia:Ping_(networking_utility)|ping]]</code> ([[1983]]) command is available in almost all operating systems. The command-line options of the ping utility and its output vary between the numerous implementations. Options may include among others:
* Count of tests: (<code>-c</code>)<ref>https://linux.die.net/man/8/ping</ref> (Linux and macOS), (<code>-n</code> Windows)
* Size of the payload
* Limits for the number of network hops (<code>[[TTL]]</code>) that probes traverse
Timing options:
* Timeout for exiting: <code>[[-t]]</code> (macOS), Linux not implemented.
* [[Interval]] between the requests <code>-i</code> (macOS)
* Time to wait for a response (<code>-W</code>) miliseconds for macOS and seconds for Linux
Output format:
* Include [[timestamp]] on each line: Linux (<code>-D</code>)
