NPROC(1)

📦 version 0.12.0, in arch rolling

bestie, welcome to the NPROC(1) page from the General Commands Manual — it’s giving tiny-but-mighty core-counting energy 💅✨

🌸 NAME 🌸

nproc — Print the number of cores available to the current process. If the OMP_NUM_THREADS or OMP_THREAD_LIMIT environment variables are set, then they will determine the minimum and maximum returned value respectively. no cap, that’s the whole errand 💖

✨ SYNOPSIS ✨

nproc [OPTIONS]...

that’s the whole recipe, bestie 🎀

🦋 DESCRIPTION 🦋

okay so here’s the tea: this prints the number of cores available to the current process. If the OMP_NUM_THREADS or OMP_THREAD_LIMIT environment variables are set, then they will determine the minimum and maximum returned value respectively. literally that’s it, and it ate 💅

💜 OPTIONS 💜

  • --all — print the number of cores available to the system
  • --ignore <N> — ignore up to N cores. [default: 0]
  • -h, --help — Print help
  • -V, --version — Print version

ngl, the default for --ignore is 0, so bestie starts with zero ignored cores unless you say otherwise 🫶
