Parent dir path in Ruby

In Ruby, we can get the parent directory path of a given path by using the File.dirname method.

Here's an example:

path = "/home/user/documents/report.pdf"
parent_dir_path = File.dirname(path)
puts parent_dir_path

Output:

/home/user/documents

In the above code, we have assigned a path of a file to the path variable. Then, we have used the File.dirname method to get the parent directory path of the file.

This method returns the directory path of the file, without including the file name (if any) in it. Hence, we get the string "/home/user/documents", which is the path of the parent directory of the file report.pdf.
