Process & Resource Monitoring (Top/Htop/Ps/Systemd)

Stop wasting screen space on process threads you do not care about

🧩 The Challenge

Dealing with a Java application or a web server that spawns fifty threads makes reading top or htop an absolute nightmare. I have wasted way too much time scrolling past identical thread IDs just to find the parent process eating all my RAM.

💡 The Fix

Use the specific ps flags to filter out those individual threads and keep your process tree clean. It makes spotting the actual process hog instant.

ps -eo pid,ppid,cmd --forest --no-headers --sort=-%mem | grep -v "\[" | head -n 20

⚙️ Why It Works

Tossing in –forest shows you the actual relationship between processes, while the grep filter strips out those kernel-level threads that usually just clutter your view. It clears the noise so you can see what is actually taxing your system.

🚀 Pro-Tip: Alias this to pss in your bashrc so you can stop typing the long version every time your load average spikes.
