The commands are divided into two types: general commands and app commands.

General commands

General commands operate on your Heroku account as a whole, and are not specific to a particular app. For instance, to get a list of apps you created or are a collaborator on:

$ heroku apps
example
collabapp                 owner@example.org
example2

App commands

App commands are typically executed from within an app’s local git working copy. The app name is automatically detected by scanning the git remotes for the current working copy, so you don’t have to specify which app to operate on explicitly. For example, the heroku apps:info command can be executed without any arguments inside the working copy:

$ cd example
$ heroku apps:info
=== example
Git Repo:       git@heroku.com:example.git
Owner:          you@example.org
Repo size:      960k
Slug size:      512k
Stack:          cedar-14
Web URL:        http://example.heroku.com/

If you have multiple heroku remotes or want to execute an app command outside of a local working copy, you can specify an explicit app name as follows:

$ heroku apps:info --app example

Using an HTTP proxy

If you’re behind a firewall that requires use of a proxy to connect with external HTTP/HTTPS services, you can set the HTTP_PROXY or HTTPS_PROXY environment variables in your local developer environment, before running the heroku command. For example, on a Unix system you could do something like this:

$ export HTTP_PROXY=http://proxy.server.com:portnumber
or
$ export HTTPS_PROXY=https://proxy.server.com:portnumber
$ heroku login

On a Windows machine, either set it in the System Properties/Environment Variables, or do it from the terminal:

> set HTTP_PROXY=http://proxy.server.com:portnumber
or
> set HTTPS_PROXY=https://proxy.server.com:portnumber
> heroku login
