1
2
3
4
5

# Change to a different directory
Dir.chdir('/path/to/directory')

# Check the current working directory
puts Dir.pwd

How do I specify a different path in jruby?

To specify a different path in JRuby, you can use the -J-D option to set a Java system property. Follow these steps to specify a different path in JRuby:

1. Open your terminal or command prompt.
2. Use the following command structure to set the path: jruby -J-DpropertyName=value scriptname.rb Replace propertyName with the name of the Java system property you want to set, value with the new path you want to specify, and scriptname.rb with the name of the JRuby script you want to run.
3. For example, if you want to specify a different load path for your JRuby script, you can use the following command: jruby -J-Djruby.lib=path/to/libraries scriptname.rb
4. Run the command, and JRuby will use the specified path for the script you are running.

How to change the working directory in jruby?

In JRuby, you can change the working directory by using the Dir class. Here's how you can do it:

1. Use the Dir.chdir method to change the working directory to a specific path. For example:

1

Dir.chdir("/path/to/directory")

1. You can also use a block to change the working directory temporarily and then return to the original working directory once the block is executed. For example:

1
2
3

Dir.chdir("/path/to/directory") do
  # Code to be executed in the new working directory
end

1. To get the current working directory, you can use the Dir.pwd method. For example:

1
2

current_directory = Dir.pwd
puts "Current working directory: #{current_directory}"

By using these methods, you can easily change and retrieve the working directory in JRuby.
