Parent dir path in Groovy

In Groovy, you can get the parent directory path of a file or directory using the getParent() method of the File class. Here's an example:

def file = new File('/path/to/myfile.txt')
def parentDir = file.getParent()
println "Parent directory: $parentDir"

Output:

Parent directory: /path/to

You can also get the parent directory path directly from a string path using the getParent() method of the Paths class. Here's an example:

import java.nio.file.Paths
def pathString = '/path/to/myfile.txt'
def parentDir = Paths.get(pathString).getParent().toString()
println "Parent directory: $parentDir"

Output:

Parent directory: /path/to

Note that both examples assume that the file or directory exists. If the file or directory doesn't exist, the getParent() method will return null.
