Well, upon revisiting this project I now realize how dramatically over engineered it is, so i'm deprecating this but leaving it up for the lolz. Use something like: https://gist.github.com/mikeflynn/4278796

goodhost

hosts, for good

For now, only via the Go toolchain:

set

23:28:15: /Users/foodbuttondev/workspace/gocode/src/github.com/foodbutton/burritobutton (master*) 
 → goodhost set 67.211.203.213 grafana.foodbutton.io "grafana"

# /etc/hosts
...
67.211.203.213	grafana.foodbutton.io	# grafana

remove

Remove an entry by network address.

23:28:15: /Users/foodbuttondev/workspace/gocode/src/github.com/foodbutton/burritobutton (master*) 
 → goodhost remove 67.211.203.213

label

Add or replace the label of an existing entry.

23:28:15: /Users/foodbuttondev/workspace/gocode/src/github.com/foodbutton/burritobutton (master*) 
 → goodhost label 119.104.50.216 "api v2"

# /etc/hosts
...
119.104.50.216	api.foodbutton.io	# api v2

Addendum

Nervous? Testing? Have a workflow you're ashamed of? By default goodhost messes with /etc/hosts, but you can use the --file, -f flag or set your $HOSTS_FILE environment variable to change what file goodhost manipulates.

ToDo

• Flag to output list in JSON format
• Get by label
• Validate network addresses
