✨ ypwhich — the manual, but make it make sense ✨

okay bestie, gather round 💖 this is ypwhich, and its whole entire job is to return the name of the NIS server or the map master. that's it. that's the gig. she's a little lookup queen and she ate 💅

🌸 SYNOPSIS 🌸

ypwhich [ -d domain ] [ -Vn ] [ hostname ]
ypwhich [ -d domain ] [ -t ] -m [ mname ]
ypwhich -x

three whole fits. pick your vibe ✨

🦋 DESCRIPTION 🦋

so like, ypwhich comes back with the name of the NIS server that's supplying NIS services to a NIS client — or, if you're asking about a map, it tells you which server is the master for that map. no cap. 👑

if you just run it with no arguments at all, it gives you the NIS server for the local machine. simple. iconic. and if you pass a hostname, it goes and queries that machine instead to find out which NIS master it is using. it's giving "who's your server, bestie?" 🫶

💖 OPTIONS 💖

  • -d domain — specify a domain that is not the default domain. main character domain energy, go off 🎀
  • -t — this one inhibits map nickname translation. like, no nicknames today, we're going full legal name 😤
  • -m mname — find the master NIS server for a map. ⚠️ heads up bestie: you cannot specify a hostname alongside the -m option, so don't even try it 🙈. mname can be a mapname or a nickname for a map. and if you omit mname entirely? ypwhich will produce a list of available maps for you. a little gift. a little treat. 🍓
  • -x — display the map nickname translation table. the receipts, the lore, the whole dictionary 📖✨
  • -Vn — version of ypbind(8). V3 is the default. use V2 for NIS clients that don't support IPv6. respectfully, if that's you, upgrade bestie 😭

🧚 FILES 🧚

  • /var/yp/nicknames — the map nickname translation table. this is where the nicknames live. the group chat of map names 💜
