通过输入man bash，我们可以看到

FILES
       /bin/bash
              The bash executable
       /etc/profile
              The systemwide initialization file, executed for login shells
       /etc/bash.bashrc
              The systemwide per-interactive-shell startup file
       /etc/bash.bash.logout
              The systemwide login shell cleanup file, executed when a login shell exits
       ~/.bash_profile
              The personal initialization file, executed for login shells
       ~/.bashrc
              The individual per-interactive-shell startup file
       ~/.bash_logout
              The individual login shell cleanup file, executed when a login shell exits
       ~/.inputrc
              Individual readline initialization file

“per-interactive-shell”是什么意思？特别是，这里的“per”是什么意思？这里的“per”是“每个”的意思吗？每个交互式shell？还是有别的意思？

“单独的每个交互式外壳启动文件”是否意味着“每个交互式外壳的单独启动文件”？

我想让我的 Linux 设备将其本地时间与另一台 Linux 服务器的本地时间同步，而无需任何其他参考。我不在乎实际时间。我想要我的假时间。因此我不需要任何其他 ntp 服务器作为参考。例如，我只是将我的 Linux 服务器的本地时间设置1.2.3.4为2033-02-23 15:23:10. 这次我想让我的 Linux 设备同步。/etc/ntp.confLinux服务器上的配置文件是：

restrict 127.0.0.1 
restrict ::1

server 127.127.1.1
fudge  127.127.1.1 stratum 8

disable monitor
logfile /var/log/ntp/ntp.log
pidfile /var/run/ntpd.pid
driftfile /var/lib/ntp/drift
leapfile /etc/ntp.leapseconds

在 Linux 客户端上，我键入ntpdate 1.2.3.4，然后它给了我错误：

 5 Feb 08:26:39 ntpdate[31059]: no server suitable for synchronization found

这是为什么？我已经测试了-d参数 ie ./ntpdate -d 1.2.3.4，它说：

 5 Feb 08:40:54 ntpdate[22958]: ntpdate [email protected] Mon Feb  5 10:02:23 UTC 2018 (1)

它有什么问题？我怎么解决这个问题？
