Delete a file

In this task, the job is to delete a file called "input.txt" and delete a directory called "docs". This should be done twice: once "here", i.e. in the current working directory and once in the filesystem root.

Forth

There is no means to delete directories in ANS Forth.

 s" input.txt" delete-file throw
s" /input.txt" delete-file throw

Haskell

import System.IO
import System.Directory

main = do
  removeFile "output.txt"
  removeDirectory "docs"
  removeFile "/output.txt"
  removeDirectory "/docs"

Java

import java.util.File;
public class FileDeleteTest {
   public static boolean deleteFile(String filename) {
       boolean exists = new File(filename).delete();
       return exists;
   }
   public static void test(String type, String filename) {
       System.out.println("The following " + type + " called " + filename + 
           (deleteFile(filename) ? " was deleted." : " could not be deleted.")
       );
   }
   public static void main(String args[]) {
        test("file", "input.txt");
        test("file", File.seperator + "input.txt");
        test("directory", "docs");
        test("directory", File.seperator + "docs" + File.seperator);
   }
}

MAXScript

Perl

use File::Spec::Functions qw(catfile rootdir);
# here
unlink 'input.txt';
rmdir 'docs';
# root dir
unlink catfile rootdir, 'input.txt';
rmdir catfile rootdir, 'docs';

Without Perl Modules

'Current Directory
IO.Directory.Delete("docs")
IO.Directory.Delete("docs", True) 'also delete files and sub-directories
IO.File.Delete("output.txt")

'Root
IO.Directory.Delete("\docs")
IO.File.Delete("\output.txt")

'Root, platform independent
IO.Directory.Delete(IO.Path.DirectorySeparatorChar & "docs")
IO.File.Delete(IO.Path.DirectorySeparatorChar & "output.txt")
