Create a file

Create a file
You are encouraged to solve this task according to the task description, using any language you may know.

In this task, the job is to create a new empty file called "output.txt" of size 0 byte and an empty directory called "docs". This should be done twice: once "here", i.e. in the current working directory and once in the filesystem root.

Bash

 touch output.txt
 touch /output.txt
 mkdir docs
 mkdir /docs

DOS

 md docs
 md \docs

Forth

There is no means to create directories in ANS Forth.

 s" output.txt" w/o create-file throw ( fileid) drop
s" /output.txt" w/o create-file throw ( fileid) drop

Java

import java.util.File;
public class CreateFileTest {
   public static String createNewFile(String filename) {
       try {
           // Create file if it does not exist
           boolean success = new File(filename).createNewFile();
           if (success) {
               return " did not exist and was created successfully.";
           } else {
               return " already exists.";
           }
       } catch (IOException e) {
               return " could not be created.";
       }
   }
   public static void test(String type, String filename) {
       System.out.println("The following " + type + " called " + filename + 
           createNewFile(filename)
       );
   }
   public static void main(String args[]) {
        test("file", "output.txt");
        test("file", File.seperator + "output.txt");
        test("directory", "docs");
        test("directory", File.seperator + "docs" + File.seperator);
   }
}

Perl

use File::Spec::Functions qw(catfile rootdir);
{ # here
    open my $fh, '>', 'output.txt';
    mkdir 'docs';
};
{ # root dir
    open my $fh, '>', catfile rootdir, 'output.txt';
    mkdir catfile rootdir, 'docs';
};

Without Perl Modules

Current directory

perl -e 'qx(touch output.txt)'
perl -e 'mkdir docs'

Root directory

perl -e 'qx(touch /output.txt)'
perl -e 'mkdir "/docs"'

Python

Current directory

import os
f = open("output.txt", "w")
f.close()
os.mkdir("docs")

Root directory

os.mkdir("docs")
f = open("/output.txt", "w")
f.close()
os.mkdir("/docs")

Tcl

Assuming that we're supposed to create two files and two directories (one each here and one each in the file system root) and further assuming that the code is supposed to be portable, i.e. work on win, linux, MacOS (the task is really not clear):

close [open output.txt w] 
close [open [file nativename /output.txt] w] 

file mkdir docs
file mkdir [file nativename /docs]

Toka

 needs shell
 " output.txt" "W" file.open file.close
 " /output.txt" "W" file.open file.close

 ( 511 is the decimal equivilient of mode 777)
 " docs" 511 mkdir
 " /docs" 511 mkdir
