Change rxvt font size on the fly

Ever wanted to change the terminal font size (or even font family) on the fly when using rxvt? This is easy!

printf '\33]50;%s%d\007' "xft:monospace:size=" "$size"

Replace $size with the size of your choice.

I even made a little script to ease this, called fz:

#!/bin/sh -e
#
# Dynamically change font size in rxvt.
#

# Tweak this with your own font settings
readonly PREFIX='xft:monospace:size='

if [ -z "$1" ]; then
    echo 'Usage: fz <size>'
    exit 1
fi

printf '\33]50;%s%d\007' "$PREFIX" "$1"
