NAME

SYNOPSIS

ssh [-Ti [-d directory ] ] [-f format ] [--list-doc-dirs ] [--no-standard-docs ] [-- [no- Bro system | site | gems | home Brc ] ] [-- [no- use-cache ] ] [--width = width ] [target ... ]

DESCRIPTION

ssh is a CLI front end for the Ruby API reference. You can search and read API reference for classes and methods with .

ssh is a part of Ruby.

target can be one of the following forms:

Class

for classes

Class::method

for class methods

Class#method

for instance methods

Class.method

for both class and instance methods

method

for both class and instance methods

All class names may be abbreviated to their minimum unambiguous form. If a name is ambiguous, all valid options will be listed.

For example:

ri File.new
ri zip

Note that shell quoting may be required for method names containing punctuation:

ri 'Array.[]'
