gotop

Another TUI graphical activity monitor, inspired by vtop and gtop, this time written in Go!
Built with gopsutil, drawille-go, and a heavily modified version of termui which uses termbox-go.

Installation

Go compiles to a single executable so you just need to get that into your $PATH.

To download the latest binary for your OS into /usr/bin, you can run the install script:

curl https://raw.githubusercontent.com/cjbassi/gotop/master/install.sh | sudo bash

If you install this way, starting gotop with the -u flag will update if there's a newer version.

To uninstall:

sudo rm /usr/bin/gotop

Currently only tested on Arch Linux x86_64, so create an issue if the binary for your OS doesn't work or if there isn't one.

Arch Linux

Alternatively, if you're on Arch Linux you can install the gotop package from the AUR.
