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
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
There's no way to delete folders in MAXScript
-- Here deleteFile "input.txt" -- Root deleteFile "\input.txt"
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';

Current directory
perl -e 'unlink input.txt' perl -e 'rmdir docs'
