💖 SM2FILE(1) 💖

okay bestie, so this is a page from the ICI executables manual set, and it's about a lil program called sm2file. it's giving very much "test program that goes hard" energy. let's get into it 🫶

✨ NAME ✨

sm2file — shared-memory linked list data extraction test program

like. that's the whole job. it extracts. it tests. it's an icon. 👑

🌸 SYNOPSIS 🌸

sm2file

no flags, no args, no drama. she just runs. periodt. 💅

🦋 DESCRIPTION 🦋

so sm2file stress-tests shared-memory linked list data extraction. what does that mean fr fr? it retrieves and deletes all text file lines that were inserted into a shared-memory linked list — and that list is the root object of a PSM partition named "file2sm". yes, that's the exact name, keep it. 🌈

the way sm2file operates echoes the cyclical operation of file2sm — they're like a duo, main character energy x2 ✨. the EOF lines that file2sm inserts into the linked list are basically punctuation marks for the writing of files that are copies of file2sm's original source text file. so each EOF line is like "okay next chapter 💅".

the name of every file that sm2file writes is file_copy_cycleNbr, where cycleNbr is, in effect, the count of EOF lines encountered in the linked list up to the point at which the writing of this file began. so like, first file = cycle 1, second = cycle 2, you get it, iykyk. 🎀

and here's the cute part (or the annoying part, depending): sm2file may catch up with the data ingestion activity of file2sm. and if that happens? she blocks — specifically she takes the file2sm test semaphore — and just waits until the linked list is no longer empty. no cap. she will sit there. patiently. like a bestie waiting for you outside the bathroom. 😭

💀 EXIT STATUS 💀

  • "0" — sm2file has terminated. that's it. that's the whole status. she's done. 🎉

🍓 FILES 🍓

No configuration files are needed.

literally none. zero. she's low maintenance. 🌸

🧚 ENVIRONMENT 🧚

No environment variables apply.

nope, not a single one. she doesn't need your $PATH opinions. 💜

🔥 DIAGNOSTICS 🔥

here's where she gets a lil chatty when things go wrong. every single one, coming up:

  • can't attach to shared memory — Operating system error. Check errtext, correct problem, and rerun. 😭
  • Can't manage shared memory. — PSM error. Check for earlier diagnostics describing the cause of the error; correct problem and rerun.
  • Can't create shared memory list. — PSM error. Check for earlier diagnostics describing the cause of the error; correct problem and rerun.
  • Can't create semaphore. — ION system error. Check for earlier diagnostics describing the cause of the error; correct problem and rerun.
  • Can't open output file — Operating system error. Check errtext, correct problem, and rerun.
  • can't write to output file — Operating system error. Check errtext, correct problem, and rerun.
ngl bestie if you're seeing a bunch of these, the move is: read the earlier diagnostics, fix the actual problem, then rerun. don't just spam rerun and hope. 🙈

and that's the whole page, bestie!! this was perl v5.24.1, dated 2016-07-07, from the ICI executables set. she's vintage, she's reliable, she extracts shared-memory linked list data and she does it flawlessly. slay 💖✨🎀
