realpath: Require all path components to exist.
$ realpath --canonicalize-existing ${filename_or_directory}
try on your machine
The realpath command is used to resolve the absolute path of a file or directory. It returns the canonicalized absolute pathname of the given file or directory name.
In the provided command, --canonicalize-existing is an option used with realpath to only canonicalize the existing files or directories. This means that if a given path is a symbolic link, the canonicalized path returned will follow that link and resolve to the actual file or directory it points to.
${filename_or_directory} is a placeholder representing the name or path of the file/directory you want to get the canonicalized path for. You should replace it with the actual file or directory name or path you want to resolve.
