Description

Turn absolute Windows paths into unix-friendly equivalent.

Parameter

Parameter	Description
pathToCheck	Path to be checked for being a Windows path with drive letter. We assume it is canonical already, so the backslashes are turned to slashes.

Return

Cleaned up Windows path.

Declaration

public static String unixizeWindowsAbsolutePath(final String pathToCheck)

     * Turn absolute Windows paths into unix-friendly equivalent. Keep as-is if not Windows absolute path.
     * Warning: A canonical version of <c>C:/hello</c> is actually <c>/C:/hello</c>. This needs to be worked out.
     * <p/>
     * Example:
     * c:something -> c/something
     * D:/test/test -> d/test/test
     * <p/>
     * Retaining the drive letter in the path prevents collisions in case multiple disk drives are used on
     * the Windows host. Removing the colon ensures friendly paths (colon is a special character).
     *
     * @param pathToCheck Path to be checked for being a Windows path with drive letter. We assume it is canonical already, so the backslashes are turned to slashes.
     * @return Cleaned up Windows path.
