How do I schedule a timed reboot of my server in seconds?
提问by Dave
I'm using bash shell on Linux …
我在 Linux 上使用 bash shell ...
$ uname -a
Linux sandbox.mydomain.com 3.4.76-65.111.amzn1.x86_64 #1 SMP Tue Jan 14 21:06:49 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
although it would be nice if I could come up with a solution in any bash supported environment. My question is, in my script I want to scheduled a delayed reboot of my server in 5 seconds. So far, I have the below, but it takes 60 seconds …
尽管如果我能在任何支持 bash 的环境中提出解决方案，那就太好了。我的问题是，在我的脚本中，我想在 5 秒内安排延迟重启我的服务器。到目前为止，我有以下内容，但需要 60 秒……
# Timed reboot of server
sudo shutdown -r 1
# Fail if any of the sub-deployments failed.
if [[ ( $PROC1_STATUS -ne 0 ) ||
( $PROC2_STATUS -ne 0 ) ||
( $PROC3_STATUS -ne 0 ) ]]
then
exit 1;
fi
Does anyone know how I can adjust the above except make the timed reboot in 5 seconds instead of a minute? The solution doesn't have to use "shutdown" but it was the only tool I could find.
有谁知道除了在 5 秒而不是一分钟内进行定时重启之外，我可以如何调整上述内容？该解决方案不必使用“关机”，但它是我能找到的唯一工具。
