       ri1.9 - Ruby Information at your fingertips


       ri1.9 [options] [names...]


       ri1.9 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 File
           ri1.9 F.n
           ri1.9 zip

       Note that shell quoting may be required for method names containing punctuation:
           ri1.9 'Array.[]'

       --classes, -c
              Display the names of classes and modules we know about.

       --doc-dir, -d dirname
              A directory to search for documentation. If not specified, we search  the  standard

       --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-names, -l
              List all the names known to RDoc, one per line.

       --no-pager, -T
              Send output directly to stdout.

       --width, -w width
              Set the width of the output.

       --version, -v
              Display the version of ri1.9.

       --help, -h
              Display help.

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