issetuid(path) -> Bool

Returns true if path has the setuid flag set, false otherwise.


  1. Check if a file has the setuid flag set:

    julia> issetuid("/path/to/file")

    This example checks if the file at the given path has the setuid flag set.

  2. Verify if a directory has the setuid flag set:

    julia> issetuid("/path/to/directory")

    It returns false since directories typically do not have the setuid flag set.

  3. Handle non-existent paths:
    julia> issetuid("/non/existent/path")

    When the specified path does not exist, issetuid returns false.

Common mistake example:

julia> issetuid("/etc/passwd")
ERROR: IOError: permission denied (EACCES)

In this example, the user does not have the necessary permissions to access the file at /etc/passwd. It's important to ensure that the user has sufficient privileges to avoid such errors when using issetuid.
