=={{header|Lua}}==
The ubiquitous luafilesystem module contains lfs.mkdir but this does not have an option equivalent to the posix mkdir -p.
Instead, the function shown here uses package.config to determine the correct directory separator for the OS and then iterates over the path string to create each individual folder in turn.
<syntaxhighlight lang="lua">require("lfs")
function mkdir (path)
local sep, pStr = package.config:sub(1, 1), ""
for dir in path:gmatch("[^" .. sep .. "]+") do
pStr = pStr .. dir .. sep
lfs.mkdir(pStr)
end
end
mkdir("C:\\path\\to\\dir") -- Quoting backslashes requires escape sequence</syntaxhighlight>
Note that attempting to run lfs.mkdir for a path that already exists writes no changes to disk and returns nil.

Above is a modified version of the standard library's <code>os.makedirs</code>, for pedagogical purposes. In practice, you would be more likely to use the standard library call:
<syntaxhighlight lang="python">

In Python3 this becomes even simpler:
<syntaxhighlight lang="python">

(formerly Perl 6)
{{Works with|rakudo|2016.06}}
There is a built-in function for this:
<syntaxhighlight lang="raku" line>mkdir 'path/to/dir'</syntaxhighlight>
Alternatively, a custom solution (as per task description) that only uses the built-in <tt>mkdir</tt> non-recursively. The "triangle reduce" meta-operator <code>[\ ]</code> is used get the intermediate results of a left fold with the comma operator on the list of path elements.
<syntaxhighlight lang="raku" line>for [\,] $*SPEC.splitdir("../path/to/dir") -> @path {
mkdir $_ unless .e given $*SPEC.catdir(@path).IO;

=={{header|REXX}}==
The following works with any modern (Microsoft) Windows ® and/or DOS.
Operating system note: all versions of Microsoft ® DOS require the use of a blackslash [<big><big>'''\'''</big></big>] instead of a forward slash [<big><big>'''/'''</big></big>].
Usage note: without the error messages being suppressed, the '''MKDIR''' command will issue an error message if the subdirectory (or its path) already exists.
<syntaxhighlight lang="rexx">/*REXX program creates a directory (folder) and all its parent paths as necessary. */
trace off /*suppress possible warning msgs.*/
dPath = 'path\to\dir' /*define directory (folder) path.*/
'MKDIR' dPath "2>nul" /*alias could be used: MD dPath */
/*stick a fork in it, we're done.*/</syntaxhighlight>

FILE ACCESSOR methods
#handle HASANSWER() - Return non-zero if the file accessor has at least one
resulting row.
#handle ROWCOUNT() - Return the number of rows returned.
#handle NEXTFILE$() - Advance to the next row and return a comma delimited string for the next file (name, size, date, time, directory flag).
#handle NEXTFILE$([delimExpr$]) - Like NEXTFILE$() but you get to specify the delimiter instead of a comma.
#handle NAME$() - Return the name of the current file row.
#handle SIZE() - Return the size of the current file row.
#handle DATE$() - Return a string containing a formatted date for the current file row.
#handle TIME$() - Return a string containing a formatted time for the current file row.
#handle ISDIR() - Return non-zero if the current file row represents a directory instead of a file.
#handle RESET() - Reset the file accessor back to the beginning so you can read through them again.
#handle DATEFORMAT(template$) - Set the date format using a "mmm dd, yyyy" style template$.
#handle TIMEFORMAT(template$) - Set the time format using a "hh:mm:ss" style template$.
#handle ISNULL() - Returns zero (or false)
#handle DEBUG$() - Returns the string "Files"

=={{header|Seed7}}==
The library [http://seed7.sourceforge.net/libraries/cli_cmds.htm cli_cmds.s7i]
defines the function doMkdirCmd, which is used below.
<syntaxhighlight lang="seed7">$ include "seed7_05.s7i";
include "cli_cmds.s7i";
const proc: main is func
begin
doMkdirCmd(argv(PROGRAM), TRUE);
end func;</syntaxhighlight>
The library cli_cmds.s7i defines also
[http://seed7.sourceforge.net/libraries/cli_cmds.htm#doMkdir%28inout_string%29 doMkdir] (Make directories like the Unix mkdir command)
and [http://seed7.sourceforge.net/libraries/cli_cmds.htm#doMd%28inout_string%29 doMd] (Make directories like the DOS md command).
This functions read the parameters and options from a string.
The reading is done according to Unix respectively DOS/Windows rules.
The function doMkdir is used in the alternate solution below:
<syntaxhighlight lang="seed7">$ include "seed7_05.s7i";
include "cli_cmds.s7i";
const proc: main is func
local
var string: parameters is "";
begin
parameters := join(argv(PROGRAM), " ");
doMkdir(parameters);

Tcl's built in <code>file mkdir</code> works exactly this way:
<syntaxhighlight lang="tcl">file mkdir ./path/to/dir</syntaxhighlight>
If a directory cannot be made (e.g., because it would involve making a directory with the same name as an existing file) the command will throw a trappable error, as normal for Tcl commands.

Curiously, this can only be done at present from a DOME program. A minimal script to do it would be:

}
update() {}

}
var Game = Main.new()</syntaxhighlight>

However, this functionality is expected to be added to Wren-cli in the next version. The code needed will be as follows:
<syntaxhighlight lang="wren">import "io" for Directory
Directory.create("path/to/dir")</syntaxhighlight>
