In JRuby, you can change the working directory using the Dir class. To change the working directory, you can use the Dir.chdir method followed by the path to the directory you want to change to. For example, if you want to change the working directory to a directory named "my_directory", you can use Dir.chdir("my_directory"). This will change the working directory to the "my_directory" directory. Additionally, you can use the Dir.getwd method to get the current working directory.

What is the behavior of jruby when the specified directory does not exist?
If a specified directory does not exist, JRuby will typically throw an exception or error indicating that the directory could not be found. The specific error message will depend on the context in which the directory is being referenced. It is always a good practice to check if a directory exists before trying to access or manipulate files within it in order to avoid such errors.
How to set the working directory in a jruby script?
To set the working directory in a JRuby script, you can use the "Dir.chdir" method. Here's an example code snippet that demonstrates how to set the working directory to a specific path:
1 2 3 4 5 |
# Set the working directory to a specific path Dir.chdir("/path/to/directory") # Now, the working directory is set to the specified path puts "Current working directory: #{Dir.pwd}" |
In this code snippet, the Dir.chdir method is used to change the working directory to the specified path ("/path/to/directory"). After changing the working directory, the Dir.pwd method is used to retrieve and print the current working directory path.
