MEMEXIST(1)

💅 MEMEXIST(1) — libmemcached-awesome, bestie edition

okay so first things first, this whole page is memexist, and it straight-up lives in the libmemcached docs family. If you've been looking for the "does this key even exist" detector, congrats babe, you found her. ✨

🌸 NAME

memexist — literally the libmemcached Documentation page for it. That's the whole name section, no notes. 💅

---

🦋 SYNOPSIS

memexist [options] <key>

Check for the existence of a key. That's it. That's the job.

---

✨ DESCRIPTION

So memexist checks for the existence of a key within a cluster. She pokes the cluster, asks "hey is this key in there," and reports back. Simple queen behaviour, no cap. 👑

🎀 OPTIONS

• -h, --help — Display help. Your "what do I even do here" button. 🫶
• -V, --version — Display version. Identity check, love that for her.
• -q, --quiet — Operate quietly. Shy lil vibe. 🤫
• -v, --verbose — Operate more verbosely. Now she's oversharing and honestly? We're listening.
• -d, --debug — See -v, --verbose. Same energy, different flag. 💀
• -s, --servers <list of servers> — Specify the list of servers as hostname[:port][,hostname[:port]...]. Yes, that exact format, copy it, don't freestyle it. ✨
• -n, --non-blocking — Enable non-blocking operations. She doesn't wait around, main character energy fr.
• -N, --tcp-nodelay — Disable Nagle's algorithm. No more batching and holding it in, we go now. 🔥
• -b, --binary — Enable binary protocol. Binary era, iconic. 🖤
• -B, --buffer — Buffer requests. Collect them, save them up, cute little stack. 🎀
• -u, --username <username> — Use username for SASL authentication. Gotta show ID at the door. 🪪
• -p, --password <password> — Use password for SASL authentication. The other half of the secret handshake. 🔐
• -H, --hash <algorithm> — Use algorithm as key hash algo. See memcached_behavior_t::MEMCACHED_BEHAVIOR_HASH. Yes, that's the exact name, don't shorten it, iykyk. 💅

🌈 ENVIRONMENT

• MEMCACHED_SERVERS — Specify a list of servers. Set it in your environment and she'll just know. 🧚

💜 NOTES

🧁 PROGRAM PREFIX

The prefix of this program is variable, i.e. it can be configured at build time. So she can literally go by a different name depending on how she was built. Not me being flexible and mysterious. 🙈

Usually the client programs of libmemcached-awesome are prefixed with mem, like memcat or memcp. That's the standard fit. ✨

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. Glow-up name change, slay. ⭐
