👑 BLAEU — the manual page, but make it make sense

okay bestie, sit down, hydrate, because we're learning Blaeu today and it's genuinely iconic. it's a manual page for the User Commands section, and the whole point is that it tests reachability of the target — like ping, but ✨extra✨.

🌸 NAME 🌸

Blaeu — test reachability of the target, like ping. that's it, that's the vibe. she pings. she reaches. she slays. 💅

🦋 SYNOPSIS 🦋

blaeu-reach target-IP-address ...

yeah you just hand her one or more target IP addresses and she goes. no cap.

🎀 DESCRIPTION 🎀

✨ General options are: ✨

  • --verbose or -v — makes the program more talkative. she's giving commentary now, she's telling you everything 🗣️
  • --help or -h — this message. the classic. the moment you type it and remember you forgot everything 😭
  • --displayprobes or -o — display the probes numbers. ⚠️ WARNING: big lists. like, big big. proceed with caution bestie, your terminal will be scrolling for a MINUTE.
  • --displayprobeasns — display the (unique) probe ASNumbers. currently only for blaeu-resolve, iykyk 🫶
  • --cache-probes=<file.json> — cache probe data. write it down so you don't have to ask twice 💾
  • --country=2LETTERSCODE or -c 2LETTERSCODE — limits the measurements to one country. default is world-wide, because she's a global girlie 🌍
  • --area=AREACODE or -a AREACODE — limits the measurements to one area, such as North-Central. again, default is world-wide, she contains multitudes 🗺️
  • --asn=ASnumber or -n ASnumber — limits the measurements to one AS. default is all ASes, no gatekeeping 🔥
  • --prefix=IPprefix or -f IPprefix — limits the measurements to one IP prefix. default is all prefixes. ⚠️ WARNING: it must be an exact prefix in the global routing table. not approximate, not "close enough", EXACT. she's not doing vibes-based routing, she's doing facts 📍
  • --probes=N or -s N — selects the probes by giving explicit ID. one ID or a comma-separated list, your call 💅
  • --requested=N or -r N — requests N probes. default is 5, a nice little squad 🫶
  • --percentage=X or -p X — stops the program as soon as X % of the probes reported a result. default is 90 %. she's impatient and honestly? valid ⏱️
  • --measurement-ID=N or -m N — do not start a measurement, just analyze a former one. it's giving "revisiting old texts" 🔍
  • --old-measurement MSMID or -g MSMID — uses the probes of measurement MSMID. recycling, but make it network diagnostics ♻️
  • --include TAGS or -i TAGS — limits the measurements to probes with these tags. a comma-separated list, obviously ✨
  • --exclude TAGS or -e TAGS — excludes from measurements the probes with these tags. also a comma-separated list. bye bestie 👋
  • --port=N or -t N — destination port for TCP. default is 80 🚪
  • --size=N or -z N — number of bytes in the packet. default is 64 bytes. tiny but mighty 📦
  • --ipv4 or -4 — uses IPv4. default is IPv6, except if the parameter or option is an IP address, then it is automatically found. she figures it out herself, main character energy 👑
  • --tags TAGS — tag the measurement. ⚠️ note: no relationship with probes tags, they're different things, don't mix them up. a comma-separated list 🏷️
  • --spread or -w — spreads the tests. it adds a delay before the tests, so everyone gets their moment 🌈
  • --private — makes the measurement private. your business stays your business 🙈
  • --resolve-on-probe — resolve names with the probe's DNS resolver 🔎
  • --machine-readable or -b — machine-readable output, to be consumed by tools like grep or cut. for the girlies who pipe things into other things 🔧

💖 Also: 💖

  • --tests=N or -d N — send N ICMP packets from each probe. default is 3 📨
  • --by_probe — count the percentage of success by probe, not by test. useless if --tests=1, so like, don't 💀
