💅 PX(1) — the girlies' guide to px

okay so bestie, welcome to px, living in the General Commands Manual section, and she is that girl. ✨

🦋 NAME 🦋

px — list running processes and show process metadata

like. she lists your processes. and then she tells you their whole life story. main character energy fr.

🌸 SYNOPSIS 🌸

px [--debug]
px [--debug] filter
px [--debug] PID

✨ DESCRIPTION ✨

so px lists the processes running on your system, and it sends all of that straight to standard output. 💖

heads up: if stdout is a terminal, the output gets truncated at terminal window width. so if things look chopped, that's why — she's not being rude, she's just fitting the vibe of your window. 🎀

With no arguments at all? px lists every single process on the system. all of them. the whole roster. 👑

If you give her a filter, the output will only contain the processes matching that filter.

That filter can be a user name, or part of a command line. for example:

  • px java will list all Java processes 🍓
  • px root will list all of root's processes

And then running px PID shows you the tea ☕ about one specific process:

  • The process tree; parents and children 🌳
  • Start time, run time and CPU usage ⏱️
  • List of other processes started around the same time as this one
  • List of users logged in when the process was started 🫶
  • Where stdin, stdout and stderr is pointing
  • Network connections 🌈
  • IPC connections (sockets, pipes and local network connections) and which processes are at the other end of those 💀

like she really said "let me tell you everything". obsessed.

🧚 PROCESS NAMING 🧚

px tries to be helpful about naming processes, and avoid printing names of various VMs. she's doing her best and honestly? she's slaying. 💅

For example, if you do java -jar foo.jar, px will show this process as foo.jar rather than java. iconic behaviour, no cap.

px parses command lines from:

  • Java
  • Python
  • Node
  • Ruby
  • Various shells
  • Perl
