copied!<p>In batch files, as in standard C programs, argument 0 contains the path to the currently executing script. You can use <code>%~dp0</code> to get only the path portion of the 0th argument (which is the current script) - this path is always a fully qualified path.</p> <p>You can also get the fully qualified path of your first argument by using <code>%~f1</code>, but this gives a path according to the current working directory, which is obviously not what you want. </p> <p>Personally, I often use the <code>%~dp0%~1</code> idiom in my batch file, which interpret the first argument relative to the path of the executing batch. It does have a shortcoming though: it miserably fails if the first argument is fully-qualified.</p> <p>If you need to support both relative <em>and</em> absolute paths, you can make use of <a href="https://stackoverflow.com/questions/1645843/batch-file-resolve-absolute-path-from-relative-path-and-or-file-name/4488734#4488734">Frédéric Ménez's solution</a>: temporarily change the current working directory. </p> <p>Here's an example that'll demonstrate each of these techniques:</p> <pre><code>@echo off echo %%~dp0 is "%~dp0" echo %%0 is "%0" echo %%~dpnx0 is "%~dpnx0" echo %%~f1 is "%~f1" echo %%~dp0%%~1 is "%~dp0%~1" rem Temporarily change the current working directory, to retrieve a full path rem to the first parameter pushd . cd %~dp0 echo batch-relative %%~f1 is "%~f1" popd </code></pre> <p>If you save this as c:\temp\example.bat and the run it from c:\Users\Public as</p> <p>c:\Users\Public>\temp\example.bat ..\windows</p> <p>...you'll observe the following output:</p> <pre><code>%~dp0 is "C:\temp\" %0 is "\temp\example.bat" %~dpnx0 is "C:\temp\example.bat" %~f1 is "C:\Users\windows" %~dp0%~1 is "C:\temp\..\windows" batch-relative %~f1 is "C:\Windows" </code></pre>
