💾 FS_MEMDUMP(1) — bestie's guide to the AFS Command Reference

okay so picture this: it's a manual page, it's fs_memdump(1), it lives in the AFS Command Reference, and it is Windows only — like, exclusively. no cap. 🪟✨

✨ NAME ✨

fs_memdump — dump AFS cache state and memory allocations, but [Windows only] bestie, don't forget that part 💅

🎀 SYNOPSIS 🎀

fs memdump [-begin|-end]

that's it. that's the whole vibe check. two flags. pick one. 🫶

🌸 DESCRIPTION 🌸

so what does this icon actually do? it dumps the state of AFS cache manager objects and statistics. literally all of it, into a dump. 📦

and here's the extra little bonus: if a checked build of the C run-time library is in use, memory allocations get included in the dump too. like a little surprise gift. 🎁 (key words: checked build, C run-time library — if you don't have that, no memory allocation tea for you 🙈)

💀 CAUTIONS 💀

this command is only available on Windows. periodt. if you're on anything else, this page is not for you, sorry babe 😭

⭐ OPTIONS ⭐

heads up bestie — one of either -begin or -end must be specified. you can't just run it raw, it needs a direction 👑

  • -begin — sets a memory checkpoint. like putting a little pin in the timeline. 📍
  • -end — creates a dump-file containing info about all the memory allocation that's happened since the -begin command was issued. so it's the -begin pin, but make it a whole scrapbook 🗂️✨

🌈 OUTPUT 🌈

if it worked, so for either -begin or -end, you get this absolute slay:

AFS memdump created

and if it did not work? oop —

AFS memdump failed

that's the whole story. created or failed, no in-between, no nuance 💀

🦋 EXAMPLES 🦋

wanna start a memory allocation dump? hit it with this:

% fs memdump -begin

and then when you're done and wanna close it out:

% fs memdump -end

see? iconic. beginning, then ending. the circle of life 🧚💜

👑 PRIVILEGE REQUIRED 👑

the person issuing this command must have AFS Client Administrator access. so like, you can't just walk in here with a regular account and start dumping memory. this is admin-only energy 🔥
