💖 PAGEIN — bestie edition 💖

okay so real talk, this is pagein from the General Commands Manual, and it's one of those tiny tools that does exactly one thing and does it with main character energy. sit down, grab a boba, let's go 🧋✨

🌸 NAME 🌸

pagein — a tool to force swapped out pages back into memory. yeah. that's it. that's the whole vibe. it drags your sleepy little pages out of swap and back into RAM where they belong 💅

✨ SYNOPSIS ✨

pagein [-a] [-h] [-p pid] [-v]

look at her. so compact. so iconic. 👑

🦋 DESCRIPTION 🦋

Pagein is a tool that forces pages that are in swap to be paged in back to memory.

and the main usecase?? literally just exercising the VM and swap subsystems, for testing purposes. that's it bestie, it's a gym membership for your kernel — no cap, it's not out here fixing your performance, it's out here doing reps 🏋️♀️✨

🎀 OPTIONS 🎀

pagein's options are as follow (and yes, we're going through all of them, no skipping, this is a safe space):

  • -a — try to page in all processes. this needs to be run with root privilege so pagein can actually reach all the processes, bestie, no sneaking in the back door. Cannot be used with the -p option. pick a lane 💀
  • -h — show help information. the classic. the "help me help you" flag 🫶
  • -p pid — page in process with process ID pid. Cannot be used with the -a option. and heads up: processes that aren't owned by the user need to be paged in by running pagein with root privilege, so if it's not yours, you need the sudo glow-up 🔥
  • -v — verbose mode. shows progress and paging in statistics, and it's super useful with the -a option because otherwise you're just sitting there like 👁️👄👁️ watching nothing happen.

🌈 EXAMPLES 🌈

Page in all processes and show progress:

sudo pagein -a -v

Page in the Xorg process:

sudo pagein -p $(pidof Xorg)

see how both of those start with sudo? that's not a suggestion bestie, that's the whole plot 😭
