K2HCOMPRESS(1)

📦 version 1.0.101, in epel 10, epel 9, fedora 43, fedora 44

💖 NAME 💖

okay so bestie, meet K2HCOMPRESS — she's the Utility Tool for K2HASH ✨ that's it, that's the name, short and iconic.

🌸 SYNOPSIS 🌸

k2hcompress [ -replace | -direct | -print ] [ OPTIONS ] FILE

like… pick one of those three modes, throw in whatever OPTIONS you need, and hand her a FILE. slay.

🦋 DESCRIPTION 🦋

so k2hcompress is a tool for compressing a K2HASH file, periodt. and here's the gag: she can compress the file while other processes are still using it — main character energy, truly — but ngl that mode is now unsupported. so don't come for her if you try it, okay?

💀 fr fr, the "compress while other processes are using it" thing is unsupported now. no cap.

🎀 OPTIONS 🎀

  • FILE — specify k2hash file path. yes she needs to know which file, obviously 💅
  • -h — display help. your bestie when you're lost 🫶
  • -replace — make and replace temporary k2hash file for compressing ✨
  • -direct — compress directly k2hash file mapped on memory 🔥
  • -print — only print area information of k2hash file 👀
  • -mask [BIT COUNT] — specify bit mask count for k2hash data
  • -cmask [BIT COUNT] — specify collision bit mask count for k2hash data
  • -elementcnt [ELEMENT COUNT] — specify element count for each k2hash table
  • -pagesize [BYTE] — specify pagesize for each k2hash internal data
  • -ext [LIBRARY PATH] — specify extension library for hash function 🧚
  • -g [ERR | WAN | INFO] — set debugging level; k2hlinetool displays debugging message for itself

🌈 ENVIRONMENT 🌈

  • K2HDBGMODE — this env var sets the debugging message level, same as the -g option. the value is set as SILENT, ERR, WAN or INFO. and when k2hlinetool catches the SIGUSR1 signal, the debugging message level gets bumpup ⬆️. the level changes in this order: SILENT, ERR, WAN, INFO, SILENT... and around and around we go 💫
  • 2HDBGFILE — this env var sets the file which is the debugging message. it's the same as the -glog option.
