Bash script to launch chromium, sleep for 20 seconds, then close quietly
提问by sifuhall
I am trying to create a bash script that will launch chromium, wait 20 seconds, then close chromium.
我正在尝试创建一个 bash 脚本，该脚本将启动铬，等待 20 秒，然后关闭铬。
This is for xbmcbuntu so I can open a site, then it will close automatically after 20 seconds (as I will have no way of closing it with just the remote control).
这是针对 xbmcbuntu 的，所以我可以打开一个站点，然后它会在 20 秒后自动关闭（因为我无法仅用遥控器关闭它）。
What I have is:
我所拥有的是：
#!/bin/bash
openbox &
/usr/bin/chromium-browser
sleep 20
killall -9 openbox
Chromium opens ok, but never closes.
Chromium 可以正常打开，但永远不会关闭。
What am i missing?
我错过了什么？

Since you are not putting chromium-browser in the background, none of the code after the chromium-browser command will execute until chromium-browser finishes execution. This should do what you want:
由于您没有将chromium-browser 置于后台，因此在chromium-browser 完成执行之前，chromium-browser 命令之后的任何代码都不会执行。这应该做你想做的：
#!/bin/bash
openbox &
openbox_pid=$!
/usr/bin/chromium-browser &
chrome_pid=$!
sleep 20
kill "$chrome_pid" "$openbox_pid"

Instead of killing openbox, you need to kill chromium-browser.
与其杀人openbox，不如杀人chromium-browser。
openbox &
openbox_pid=$!
/usr/bin/chromium-browser &
chromium_pid=$!
sleep 20
kill $chromium_pid
kill $openbox_pid
Don't use kill -9unless it's absolutely necessary.
kill -9除非绝对必要，否则不要使用。

没有测试，只是我的想法
#!/bin/bash
openbox &
#!/bin/bash openbox &
here run: script.any & #background where script.any permission is execute and contain:
#!/bin/bash
这里运行：script.any & #background 其中 script.any 权限被执行并包含：
#!/bin/bash
/usr/bin/chromium-browser
/usr/bin/chromium-browser
from this script run browser show mode
从此脚本运行浏览器显示模式
sleep 20 killall -9 openbox
睡眠 20 killall -9 openbox
