Either path refers to an existing directory. ,[ENOTDIR, EISDIR, EINVAL, EEXIST, ENOTEMPTY] old new copies the existing file from old to new . If the new7 file already exists, it is atomically replaced by the oldL file. Neither path may refer to an existing directory. The permissions of old are copied to new, if possible.Given a path referring to a file or directory, returns a canonicalized path. The intent is that two paths referring to the same file/directory will map to the same canonicalized path.Note that it is impossible to guarantee that the implication (same file/dir <=> same canonicalizedPath) holds in either direction: this function can make only a best-effort attempt.The precise behaviour is that of the C realpath function GetFullPathNameW on Windows). In particular, the behaviour on paths that do not exist is known to vary from platform to platform. Some platforms do not alter the input, some do, and on some an exception will be thrown.* the current directory.Given an executable file name, searches for such file in the directories listed in system PATH. The returned value is the path to the found executable or Nothing if an executable with the given name was not found. For example (findExecutable "ghc") gives you the path to GHC.The path returned by 7 corresponds to the program that would be executed by D when passed the same string (as a RawCommand, not a ShellCommand). On Windows,  calls the Win32 function  SearchPathE, which may search other places before checking the directories in PATH. Where it actually searches depends on registry settings, but notably includes the directory containing the current executable.
