To make urxvt a little less painful to look at…
Install the terminus font:
RHEL/Rocky linux:
$ sudo dnf install terminus-fonts
Debian/Ubuntu/Mint:
$ sudo apt-get install xfonts-terminus
Update ~/.Xdefaults file:
URxvt.font: xft:Terminus:pixelsize=16:antialias=false
URxvt.depth: 32 # This line maybe not necessary?
