Stop using regular top.

Seriously, I know you’re old like I am. I get that, but it turns out there’s been ridiculous advancements in top technology, there’s two programs I just learned about today that make me feel like I’ve clearly missed out on some advancements on the command line.


Atop is an ASCII full-screen performance monitor that is capable of reporting the activity of all processes (even if processes have finished during the interval), daily logging of system and process activity for long-term analysis, highlighting overloaded system resources by using colors, etc. At regular intervals, it shows system-level activity related to the CPU, memory, swap, disks and network layers, and for every process (and thread) it shows a.o. the CPU utilization, memory growth, disk utilization, priority, username, state, and exit code.

Oh, and by the way, it’s freaking beautiful:


However, if what you want is more bars and widgets and viewable doohickes, I must admit, my heart lies with


This is htop, an interactive process viewer for Linux. It is a text-mode application (for console or X terminals) and requires ncurses.


But that doesn’t really do it justice. Seriously, check it out, it freaking provides real time visual bars of every single resource like CPU and ram so at a glance you can see exactly how taxed out your freaking computer is. My god, things have gotten really quite advanced since freaking truss and top, haven’t they? Have I missed any “must have” terminal utilities from the last decade, wherein I was clearly sitting around with my head up my ass?
