htop – an interactive process viewer for Unix

Posted by jpluimers on 2017/12/25

Great tool: [WayBackhtop – an interactive process viewer for Unix because it’s both interactive and supports a wide range of OSes: Linux, FreeBSD, OpenBSD and Mac OS X.

Thanks to Warren Postma who suggested it in his comment at [WayBack18 Useful Commands to Get Hardware Information on Linux – Linuxslaves.

Note that on OS X you get this warning after brew install htop :

htop requires root privileges to correctly display all running processes,
so you will need to run `sudo htop`.
You should be certain that you trust any software you grant root privileges.

On Linux you don’t get this message as there you have the /proc file system providing enough information as explained at [WayBackosx – Why does htop on Mac OS X require root privileges to see data for all processes, but on Linux it runs without root – Super User.

A workaround (involving the setuid bit) is at [WayBackRunning htop on Mac OS X needs root. Why?! | Blog | JoeNyland.me or by running visudo ensuring you don’t need a password for it at [WayBackosx – htop isn’t returning CPU or memory usage!? – Super User
