✨ System::Info::Linux 💅

okay bestie, so this whole page is about System::Info::Linux — it's the object that holds all the Linux-specific info, from the System::Info Perl fam. 🐧💖 Think of it as the Linux girlie in the group chat, she knows everything about her machine and she's not shy about it.

🌸 DESCRIPTION 🌸

🫶 $si->prepare_sysinfo

Use os-specific tools to find out more about the system. that's it, that's the whole vibe — she goes digging with whatever the OS gives her. 🔍

🌈 $si->prepare_os

Use os-specific tools to find out more about the operating system. same energy, different target: this one's all about the OS itself. ✨

💜 $si->linux_generic

This one snoops through /proc/cpuinfo looking for these keys, no cap:

  • "processor" — count the occurrences, that's your __cpu_count 🔢
  • "model name" — this becomes part of __cpu
  • "vendor_id" — also part of __cpu
  • "cpu mhz" — yep, part of __cpu
  • "cpu cores" — these values get added onto __cpu_count

🦋 $si->linux_arm

the ARM girlie. she also checks /proc/cpuinfo, but for these keys:

  • "processor" — count the occurrences for __cpu_count 🔢
  • "Processor" — part of __cpu
  • "BogoMIPS" — part of __cpu
not me noticing processor and Processor are two different keys here. case sensitivity said "I'm the main character". 💀

🎀 $si->linux_ppc

PowerPC time!! also reads /proc/cpuinfo, and she wants:

  • "processor" — count the occurrences for __cpu_count 🔢
  • "cpu" — part of __cpu
  • "machine" — part of __cpu
  • "clock" — part of __cpu
  • "detected" — this one alters machine if it's present 👀

⭐ $si->linux_sparc

sparc girlie reporting for duty, once again in /proc/cpuinfo:

  • "processor" — count the occurrences for __cpu_count 🔢
  • "cpu" — part of __cpu
  • "Cpu0ClkTck" — part of __cpu

👑 $si->linux_s390x

big iron icon behavior 🏆 she checks /proc/cpuinfo for:

  • "processor" — count the occurrences for __cpu_count 🔢
  • "Processor" — part of __cpu
  • "BogoMIPS" — part of __cpu

🍓 $si->prepare_proc_cpuinfo

Reads the complete /proc/cpuinfo. all of it. the whole thing. front to back, no skimming. 📖

🧚 $si->count_in_cpuinfo ($regex)

Returns the number of lines $regex matches for. 🔍

💜 $si->count_unique_in_cpuinfo ($regex)

Returns the number of lines $regex matches for. (yes bestie, the description really does say the exact same thing as the one above — we report, we don't editorialize 😭)

🌸 $si->from_cpuinfo ($key)

Returns the first value of that key in /proc/cpuinfo. just the first one, she's not scrolling past that. ✨
