dirname.bat (GPL)

This "dirname.bat" is a Windows batch program that performs the same function as as the UNIX "dirname" command. And that function is to strip the child name from the parent path. You can call this script from your own custom batch script to extract the parent path.

"dirname.bat" takes advantage of the SetNumberOfArguments.bat (GPL) script that is available on this web site. So to use "dirname.bat", you'll have to download SetNumberOfArguments.bat, if you don't already have it.

"dirname.bat" is distributed as executable source code under the GNU General Public License. Please see the license agreement elsewhere on this site.

Usage

dirname.bat "path"

Examples

> dirname "\Users\Medusa\Documents\My Games\Dawn of War 2"
\Users\Medusa\Documents\My Games

> dirname "Users\Medusa\Documents\My Games\Dawn of War 2"
Users\Medusa\Documents\My Games

I found a bug in "dirname.bat" where it would not correctly handle a remote Windows directory (a path that starts with two '\' characters). I fixed the problem in the version attached below.

I found another bug, where you only specify the name but no directory. I've fixed the code so that it outputs a '.' in such a case, which matches UNIX implementation. The fixed version is attached below.

The previous version of "dirname.bat" fails when the path contains parentheses. The version attached below fixes that problem.

Found that the last fix introduced a bug that occurs when you do not specify a parent path or if the parent path is root. I've attached the fixed version below. The following are examples of correct output.

Examples

  > dirname.bat \bin
  \
  >dirname.bat "Hello World.txt"
  .
