cap <command> [options]


Capistrano is a utility and framework for executing commands in parallel on multiple remote machines, via SSH. It uses a simple DSL (borrowed in part from Rake, that allows you to define _tasks_, which may be applied to machines in certain roles. It also supports tunneling connections via some gateway machine to allow operations to be performed behind VPN's and firewalls.

Capistrano was originally designed to simplify and automate deployment of web applications to distributed environments, and originally came bundled with a set of tasks designed for deploying Rails applications. The deployment tasks are now (as of Capistrano 2.0) opt-in and require clients to explicitly put "load 'deploy'" in their recipes.

Capistrano is a self-documenting program by giving you an extensive help listing for each command. If you think that this manual page is outdated, simply running

cap -h


Capistrano is "opinionated software", which means it has very firm ideas about how things ought to be done, and tries to force those ideas on you. Some of the assumptions behind these opinions are:

  * You are using SSH to access the remote servers.
  * You either have the same password to all target machines, or you have public keys in place to allow passwordless access to them.

Do not expect these assumptions to change.


Capistrano is extensible configurable, and it has the following configuration options:

-e --explain TAKS

Displays help (if available) for the task.

-F --default-config

Always use default config, even with -f.

-f --file FILE

A recipe file to load. May be given more than once.

-H --long-help

Explain these options.

-h --help

Display this help message.

-p --password

Immediately prompt for the password.

-q --quiet

Make the output as quiet as possible.

-S --set-before NAME=VALUE

Set a variable before the recipes are loaded.

-s --set NAME=VALUE

Set a variable after the recipes are loaded.

-T --taks

List all tasks in the loaded recipe files.

-V --version

Display the Capistrano version, and exit.

-v --verbose

Be more verbose. May be given more than once.

-X --skip-system-config

Don't load the system config file (capistrano.conf)

-x --skip-user-config

Don't load the user config file (.caprc)
