--install-for-all	Allows all users to have the same installation group permission. If this parameter is included in the installation or upgrade command, all users have the same permission on the directories and files created by the runfile installation engineer as the installation group. This parameter must be used in pair with any one among --install and --upgrade, for example, *./.run --install --install-for-all. NOTE: Only the root** user can use this parameter. Make sure the security risks are considered before you include this parameter.
--install-path=<path>	Specifies the installation path. If the global configuration file ascend_toolbox_install.info exists in the environment, the specified installation path must be the same as that saved in the global configuration file.

You can run the following command to check whether the file exists in the following directory: root user: /etc/Ascend Non-root user: ${HOME}/Ascend If you do not specify the path, the default path is used. For installation as the root user, the default installation path is /usr/local/Ascend. For installation as a non-root user, the default installation path is ${HOME}/Ascend. If this parameter is used to specify the installation directory, the running user must have the read and write permissions on the specified installation directory.
