✨ MEMEXIST 💖 (that's the memexist command, from libmemcached-awesome)

okay bestie, pull up a chair, get comfy, because we're about to find out if a key even EXISTS. that's the whole vibe. 🫶

🌸 SYNOPSIS 🌸

memexist [options] <key>

Check for the existence of a key. that's it. that's the job. lowkey iconic for how simple it is. 💅

🦋 DESCRIPTION 🦋

memexist checks for the existence of a key within a cluster. one key, one cluster, one question: does it slay or does it not exist? no cap. ✨

🎀 OPTIONS 🎀

  • -h, --help — Display help. the "helppp meee" flag. 🙈
  • -V, --version — Display version. bc sometimes you just gotta know which era you're in. ⭐
  • -q, --quiet — Operate quietly. shhh. main character doesn't need to announce everything. 🤫
  • -v, --verbose — Operate more verbosely. the exact opposite energy of -q. tell me EVERYTHING. 😭
  • -d, --debug — See -v, --verbose. literally the same thing, different font. 💀
  • -s, --servers <list of servers> — Specify the list of servers as hostname[:port][,hostname[:port]...]. where's the party at, bestie? 📍
  • -n, --non-blocking — Enable non-blocking operations. no waiting around, we keep it moving. 💨
  • -N, --tcp-nodelay — Disable Nagle's algorithm. bye bye buffering delays, we're going straight through. 🔥
  • -b, --binary — Enable binary protocol. ones and zeroes, but make it fashion. 🌈
  • -B, --buffer — Buffer requests. collecting them up like little friendship bracelets. 🎀
  • -u, --username <username> — Use username for SASL authentication. who dis, identity check. 🪪
  • -p, --password <password> — Use password for SASL authentication. your little secret, keep it safe. 🔐
  • -H, --hash <algorithm> — Use algorithm as key hash algo. See memcached_behavior_t::MEMCACHED_BEHAVIOR_HASH <#_CPPv4N20memcached_behavior_t23MEMCACHED_BEHAVIOR_HASHE>. choosing how the keys get sorted into their little homes. 🏡

🌱 ENVIRONMENT 🌱

  • MEMCACHED_SERVERS — Specify a list of servers. so you don't have to type -s every single time, you're welcome. 🫶

📝 NOTES 📝

🧚 PROGRAM PREFIX 🧚

The prefix of this program is variable, i.e. it can be configured at build time. so the name you type might not be memexist, plot twist. 😳

Usually the client programs of libmemcached-awesome are prefixed with mem, like memcat or memcp.

It can be configured, though, to replace the prefix with something else like mc, in case of that, the client programs of libmemcached-awesome would be called mccat, mccp, etc. respectively. same energy, different glow-up. ✨
