MemInfo(3)

💖 NAME 💖

Sys::MemInfo — query the total free and used physical memory. 💅

Okay so this is the MemInfo(3) page from the User Contributed Perl Documentation section, and it’s all about asking your system how much memory is doing what. 🫶

✨ SYNOPSIS ✨

use Sys::MemInfo qw(totalmem freemem totalswap);

print "total memory: ".(&totalmem / 1024)."\n";
print "free memory:  ".(&freemem / 1024)."\n";

print "total swap: ".(&totalswap / 1024)."\n";
print "free swap:  ".(Sys::MemInfo::get("freeswap") / 1024)."\n";

Like, literally copy that energy, bestie. The ampersand calls are exactly as written. 🎀

🦋 DESCRIPTION 🦋

So Sys::MemInfo returns the total amount of free and used physical memory in bytes in the totalmem and freemem variables. 💖

The total amount of free and user swap memory also comes back in the totalswap and freeswap variables. ✨

The vibe check has passed on these: it’s been tested on Linux 3.13.0, UnixWare 7.1.2, AIX5, OpenBSD 3.8, NetBSD 2.0.2, FreBSD 5.4, HPUX11, Solaris 9, Tru64 5.1, Irix 6.5, Mac OS X 10.2 darwin and Windows XP. 🧪🌸

It should work on FreeBSD 4 and Windows 9X/ME/NT/200X/Vista. Fingers crossed, bestie. 🤞💜
