Instead of sending to one target until it times out or replies, fping will\nsend out a ping packet and move on to the next target in a round-robin fashion. In the\ndefault mode, if a target replies, it is noted and removed from the list of targets to check;\nif a target does not respond within a certain time limit and/or retry limit it is designated\nas unreachable. fping also supports sending a specified number of pings to a target, or\nlooping indefinitely (as in ping ). Unlike ping, fping is meant to be used in scripts, so its\noutput is designed to be easy to parse. Current statistics can be obtained without\ntermination of process with signal SIGQUIT (^\\ from the keyboard on most systems).\n\n## TLDR\n\n> A more powerful ping which can ping multiple hosts.\n\n- List the status of all hosts within a range:\n `fping {{192.168.1.{1..254}}}`\n- List alive hosts within a subnet generated from a netmask:\n `fping {{-a|--alive}} {{-g|--generate}} {{192.168.1.0/24}}`\n- List alive hosts within a subnet generated from an IP range and prune per-probe results:\n `fping {{-q|--quiet}} {{-a|--alive}} {{-g|--generate}} {{192.168.1.1}} {{192.168.1.254}}`\n- List unreachable hosts within a subnet generated from a netmask:\n `fping {{-u|--unreach}} {{-g|--generate}} {{192.168.1.0/24}}`\n\n*Source: tldr-pages*\n\n## Sections\n\n- **NAME**\n- **SYNOPSIS**\n- **DESCRIPTION**\n- **OPTIONS** (36 subsections)\n- **EXAMPLES**\n- **AUTHORS** (1 subsections)\n- **DIAGNOSTICS**\n- **RESTRICTIONS**\n- **SEE ALSO**\n\nUse structuredContent.sections for detailed options, examples, and full documentation.\n"

"content": "Initial target timeout in milliseconds. In the default, non-loop mode, the default\ntimeout is 500ms, and it represents the amount of time that fping waits for a response\nto its first request. Successive timeouts are multiplied by the backoff factor specified\nwith -B.\n\nIn loop/count mode, the default timeout is automatically adjusted to match the \"period\"\nvalue (but not more than 2000ms). You can still adjust the timeout value with this\noption, if you wish to, but note that setting a value larger than \"period\" produces\ninconsistent results, because the timeout value can be respected only for the last ping.\n\nAlso note that any received replies that are larger than the timeout value, will be\ndiscarded.\n",
