# Capissh?

An extraction of Capistrano's parallel SSH command execution, capiche?

## About

Capissh executes commands and file transfers on remote servers in parallel.

Capissh will maintain open connections with servers it has seen when it is

sensible to do so. When the batch size is not restricted, Capissh will maintain

all connections, which greatly reduces connection overhead. Sets of commands

are run in parallel on all servers within the batch.

## Example

The interface is intentionally simple. A Capissh::Configuration object will

maintain the open sessions, which will be matched up with servers for each

command invocation.

    require 'capissh'

    servers = ['[email protected]', '[email protected]']

    capissh = Capissh.new

    capissh.run servers, 'date'

    capissh.run servers, 'uname -a'

    capissh.sudo servers, 'ls /root'

## Thank You

Huge thank you to Jamis Buck and all the other Capistrano contributors for

creating and maintaining this gem. Without them, this library would not exist,

and ruby deployment wouldn't be at the level it is today.

Most of this code is directly extracted from capistrano without modification.
