在脚本中间重新启动

Question

我在脚本的中间看到了sudo reboot --这意味着后面还有更多的命令。在reboot之后的命令可以执行时，假设reboot不在if块中，是否存在这种情况？

下面是脚本中包含reboot的部分。请注意，不涉及if块。

    sudo sysctl -p # applies sysctl.conf changes
    sudo sed -i "s/#ListenAddress 0.0.0.0/ListenAddress 0.0.0.0/" /etc/ssh/sshd_config
    sudo service ssh restart

    sudo reboot

    echo "postfix postfix/main_mailer_type        select  No configuration" | sudo debconf-set-selections
    echo "gridengine-master       shared/gridenginemaster string  hpc-master" | sudo debconf-set-selections
    echo "gridengine-master       shared/gridenginecell   string  default" | sudo debconf-set-selections
    echo "gridengine-master       shared/gridengineconfig boolean false" | sudo debconf-set-selections
    echo "gridengine-common       shared/gridenginemaster string  hpc-master" | sudo debconf-set-selections
    echo "gridengine-common       shared/gridenginecell   string  default" | sudo debconf-set-selections
    echo "gridengine-common       shared/gridengineconfig boolean false" | sudo debconf-set-selections
    echo "gridengine-client       shared/gridenginemaster string  hpc-master" | sudo debconf-set-selections
    echo "gridengine-client       shared/gridenginecell   string  default" | sudo debconf-set-selections
    echo "gridengine-client       shared/gridengineconfig boolean false" | sudo debconf-set-selections
    sudo DEBIAN_FRONTEND=noninteractive apt-get install gridengine-common gridengine-client gridengine-master -y
    sudo -u sgeadmin /usr/share/gridengine/scripts/init_cluster /var/lib/gridengine default /var/spool/gridengine/spooldb sgeadmin
    sudo service gridengine-master restart
    sudo service postfix stop
    sudo update-rc.d postfix disable

如果sudo失败，脚本将继续运行，例如，如果用户在/etc/sudoers中没有适当的权限。

该命令也可能位于if块中。如果条件不为真，则将执行脚本的其他部分。
