MISSING(1)

✨ MISSING(1) ✨

okay bestie, welcome to the missing page — it lives under User Commands, and the manual name is literally MISSING. the program it's actually about? vtkdiff. the page name and the tool name are two different girls and neither one is explaining herself. 💅

---

🎀 NAME 🎀

missing — vtkdiff

that's it. that's the entire name section. iconic brevity, no notes. 🦋

---

🌸 DESCRIPTION 🌸

so the whole page is basically the program reading its own usage message back at you, and honestly? relatable. here's how it starts:

usage: vtkdiff [options] options:

and then it dumps the whole --osh- family on you, no warning, no lube, just vibes:

• --osh-memory — print amount and stacktrace of max memory use 🧠
• --osh-time — print amount of time spend in certain functions ⏱️ (yes, "spend". that's the page's spelling, not mine, we keep it fr fr)
• --osh-time-percent — print amount of time spend in certain functions by percentage 📊
• --osh-time-chop 0.0 — only print functions whose percent time is greater than given value (e.g. --osh-time-chop=2) ✂️
• --osh-time-with-filename — add file name to function name in profile output 📁
• --osh-signal — catch signals and print a stacktrace 🚨
• --osh-fpe — enable floating-point exceptions 💀
• --osh-silent — suppress all output 🤫
• --osh-pool — use memory pooling 🏊
• --osh-self-send value — control self send threshold 📨
• --osh-mpi-ranks-per-node value — mpi ranks per node (for CUDA+MPI) 🖥️

then the page hits you with the "bestie you forgot the arguments" combo:

missing required argument <gold_dir> missing required argument <result_dir> usage: vtkdiff [options] gold_dir result_dir options:

like okay, noted. this second usage form wants gold_dir and result_dir, and the options for it are:

• -tolerance value — Overrides the default tolerance of 1.0E-6 🎯
• -Floor value — Overrides the default floor tolerance of 0.0 🧊
• -superset — Allow result_dir to have more variables thangold_dir 👑 (yes, thangold_dir, one word, no space, we are NOT fixing it, that's the original and it's staying)
• -f cmd_file — Read exodiff command file 📜
• -onestep — Each directory is one time step 👣

and then — and I need you to sit down for this — the page says THE EXACT SAME THING AGAIN:

usage: vtkdiff [options] gold_dir result_dir options:

• -tolerance value — Overrides the default tolerance of 1.0E-6 🎯
• -Floor value — Overrides the default floor tolerance of 0.0 🧊
• -superset — Allow result_dir to have more variables thangold_dir 👑
• -f cmd_file — Read exodiff command file 📜
• -onestep — Each directory is one time step 👣

same five options, same wording, twice. repetition is a love language apparently. 🙈

heads up bestie: that's genuinely the whole page. no OPTIONS section of its own, no EXAMPLES, no SEE ALSO, no EXIT STATUS, nothing. everything the page has to say, it says in DESCRIPTION, and it says half of it twice. 💖

---

💜 that's the whole thing 💜

and then the page just... ends, mid-thought, like a text you forgot to finish. the very last scrap of it is this little cliffhanger:

missing required argument <resu...

and the footer underneath it is dated July 2025, with the manual name MISSING(1) stamped on both sides like a little frame. 🫶

so yeah — that's missing, aka vtkdiff, aka the most mysterious girl at the function. she doesn't explain herself, she just prints usage twice and dips. slay, I guess. ✨🎀🦋
