root_path

Arguments

Returns

The portion of the path with the file name and any trailing directory separators removed.

Description

This function strips the final file or directory name from the path to produce its parent. Any trailing directory separators are also removed. If the path represents the root of the file system then it is unmodified.

Example

    Gamma> x = "/usr/doc/FAQ";
    "/usr/doc/FAQ"
    Gamma> x = root_path(x);
    "/usr/doc"
    Gamma> x = root_path(x);
    "/usr"
    Gamma> x = root_path(x);
    "/"
    Gamma> x = root_path(x);
