I am trying to obtain documentation using ri on my local machine. If I dont require any method in my script and I want to find information on .value or .inspect or anything that is native without calling in a method how can I look that up with ri, or even rdoc?
If you just search on the method name, you should get a list of all the objects that have it:
Code:
$ ri value
= .value
(from ruby core)
=== Implementation from Cookie
------------------------------------------------------------------------------
value()
------------------------------------------------------------------------------
Returns the value or list of values for this cookie.

All objects have a base class of Object so you can get more specific, too:
Code:
$ ri Object.inspect
= Object.inspect
(from ruby core)
------------------------------------------------------------------------------
obj.inspect -> string
------------------------------------------------------------------------------
Returns a string containing a human-readable representation of obj. By
default, show the class name and the list of the instance variables and their
values (by calling #inspect on each of them). User defined classes should
override this method to make better representation of obj. When
overriding this method, it should return a string whose encoding is compatible
with the default external encoding.

It seems $? can only contain one byte. see below:
int main()
{
return 0x12345678;
}
After I run the code and check the $? value it output 120, obviously it is the decimal of the last byte of 0x12345678. And if I return a value less than 255, the $? value seems right.

Lately there have been a lot of one-liners posted in "ruby" on the apparent assumption that mainstream unix or Linux come with "ruby. They don't.
