How do I write a sailpoint beanshell java script to read a latest file

Question

I am trying to write a java in a SailPoint beanshell where I need to read a file and rename them. But the problem is filename has appending number that changes everyday according to date, ex. SampleFile0521, SampleFile0524. And I need to read a File with latest timestamp and starts with SampleFile .

Hi srikanth, To read a file with the latest timestamp and a specific prefix in Java using the SailPoint BeanShell, you can follow these steps: import java.io.File; import java.util.Arrays; import java.util.Comparator; import java.util.regex.Pattern; 2. define directory String directoryPath = "/path/to/files"; 3. define prefix String filePrefix = "SampleFile"; 4, create a file object in directory' File directory = new File(directoryPath); 5.Create a File[] array to store all the files File[] files = directory.listFiles(); 6.Use a custom Comparator and Define a regular expression pattern to match the desired file format (prefix + date): Arrays.sort(files, Comparator.comparingLong(File::lastModified).reversed()); Pattern pattern = Pattern.compile("^" + filePrefix + "\d{4}$"); 7.erate through the sorted files File latestFile = null; for (File file : files) { if (pattern.matcher(file.getName()).matches()) { latestFile = file; break; } } Check if a matching file was found and retrieve its nam if (latestFile != null) { String latestFileName = latestFile.getName(); // Perform renaming or any other operations with the file } else { // No matching file found }
