NAME
cap -- cap is an utlity to invoke capistrano tasks. SYNOPSIS
cap <command> [options] DESCRIPTION
Capistrano is a utility and framework for executing commands in parallel on multiple remote machines, via SSH. It uses a simple DSL (bor- rowed in part from Rake, http://rake.rubyforge.org/) 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 If you think that this manual page is outdated, simply running cap -h ASSUMPTIONS
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. OPTIONS
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) SEE ALSO
