Terminal emulator, configuration

xterm

$HOME/.Xdefaults can be edited to change the settings of x11/xterm , and here are examples to change the background, foreground, and font size.

XTerm*background:black
XTerm*foreground:gray
XTerm*faceName:Mono:Size=16

Lowercase xterm also works, but using a . in place of a * doesn't in the configuration file.
