ruby catch all exceptions

To catch all exceptions in Ruby, you can use the begin and rescue keywords. Here are the steps to accomplish this:

  1. Use the begin keyword to start a block of code where you anticipate an exception might occur.

  2. Write the code that you want to execute within the begin block.

  3. Use the rescue keyword followed by the type of exception you want to catch. If you want to catch all exceptions, you can use Exception as the type.

  4. Write the code that you want to execute when the exception is caught within the rescue block.

  5. If you want to catch multiple types of exceptions, you can use multiple rescue blocks, each handling a different type of exception.

  6. If you want to catch all exceptions except certain ones, you can use rescue without specifying any exception type, followed by => and the variable name to store the exception object.

  7. Optionally, you can use the else keyword followed by code that you want to execute if no exception is raised.

  8. Optionally, you can use the ensure keyword followed by code that you want to execute regardless of whether an exception is raised or not.

Here is an example of catching all exceptions in Ruby:

begin
  # Code that might raise an exception
rescue Exception => e
  # Code to handle the exception
else
  # Code to execute if no exception is raised
ensure
  # Code to execute regardless of whether an exception is raised or not
end

Note that it's generally recommended to catch specific types of exceptions instead of catching all exceptions, as catching all exceptions can make it difficult to identify and handle specific errors.
