ri1.9.1 − Ruby Information at your fingertips
ri1.9.1 [options] [names...]
ri1.9.1 displaies information on Ruby classes, modules, and methods. You can give the names of classes or methods to see their documentation. Partial names may be given: if the names match more than one entity, a list will be shown, otherwise details on that entity will be displayed.
Nested classes and modules can be specified using the normal Name::Name notation, and instance methods can be distinguished from class methods using "." (or "#") instead of "::".
For example:
ri1.9.1 File
ri1.9.1 File.new
ri1.9.1 F.n
ri1.9.1 zip
Note that shell
quoting may be required for method names containing
punctuation:
ri1.9.1 ’Array.[]’
ri1.9.1 compact\!
−−classes, −c

−−doc−dir, −d dirname
A directory to search for documentation. If not specified, we search the standard rdoc/ri directories.
−−format, −f name
Format to use when displaying output: ansi, bs, html, plain, simple. Use ´bs’ (backspace) with most pager programs. To use ANSI, either also use the −T option, or tell your pager to allow control characters. (for example using the −R option to less.)

List all the names known to RDoc, one per line.
−−no−pager, −T
Send output directly to stdout.
−−width, −w width

Options may also be passed in the ’RI’ environment variable
