# append i3status output to the measure-net-speed’s one. the quote and escape
# magic is required to get valid JSON output, which is expected by i3bar (if
# you want colors, that is. Otherwise plain text would be fine). For colors,
# your i3status.conf should contain:
# general {
#   output_format = i3bar
# }

# i3 config looks like this:
# bar {
#   status_command measure-net-speed-i3status.bash
# }
