stdin.rb

This Ruby code snippet demonstrates reading all input from standard input ($stdin). The read method, when called on $stdin without arguments, consumes and returns the entire input stream as a single string. If no input is provided, it returns nil.

Additional Note

The line of Ruby code $stdin.read reads input from the standard input (keyboard) until the end of the file (EOF) is reached, and stores the input as a string.

Ruby code snippet

# $stdin.read
#=> nil
