+The above command uses the [mount](https://linux.die.net/man/8/mount) command to mount the Azure file share and options specific to [cifs](https://linux.die.net/man/8/mount.cifs). Specifically, the file_mode and dir_mode options set files and directories to permission `0777`. The `0777` permission gives read, write, and execute permissions to all users. You can change these permissions by replacing the values with other [chmod permissions](https://en.wikipedia.org/wiki/Chmod). You can also use other [cifs](https://linux.die.net/man/8/mount.cifs) options such as gid or uid.
