No? Confirm Before

Sanity check for your shell commands

Installing

brew tap marceloboeira/formulas
brew install marceloboeira/formulas/confirm-before

Motivation

I have recently started working with a lot of DevOps CLIs that interact with staging and production servers.

My shell setup includes aliases like:

alias ks=`kubectl --context staging`
alias kp=`kubectl --context production`

However, I frequently find myself almost running something wrong by not paying attention if its production/staging. Therefore, I decided to create this small 'command wrapper' for me to make sure if I really want to run that command against production. e.g.:

alias kp=`confirm-before kubectl --context production`

Then, ...

$ kp apply -F *
Are you sure? (y/n)

Future

I might create other sanity check levels/modes:

$ alias dangerous=`confirm-before --math dangerous --production`
$ dangerous get foo
How much is 19 - 3?

Conditionals, because it can become very annoying to confirm read-only commands...

$ alias dangerous=`confirm-before --matching delete|d|rm|apply dangerous --production`
$ dangerous delete foo
Are you sure? (y/n)
...
$ dangerous get foo -> doesn't match the regexp
