我修改了在这里找到的 shell 脚本: https://github.com/Slympp/ConanLinuxScript
但我在使用“conan_stop”函数时遇到了麻烦 该脚本在之后终止
exec kill -SIGINT $pid
该脚本成功发送了终止命令,但之后它就终止了,没有错误代码或任何内容。
脚本中的所有变量均在文件的前面定义。
功能齐全
function conan_stop {
pid=$(ps axf | grep ConanSandboxServer-Win64-Test.exe | grep -v grep | awk '{print $1}')
if [ -z "$pid" ]; then
echo "[$(date +"%T")][FAILED] There is no server to stop"
else
if [ "$discordBotEnable" = true ]; then
echo "[$(date +"%T")][SUCCESS] Discord bot is enabled"
if [ -n "$botToken" ] && [ -n "$channelID" ]; then
secLeft=$(($delayBeforeShutdown * 60))
while [ $secLeft -gt "0" ]; do
minLeft=$(($secLeft / 60))
echo "[$(date +"%T")][WAIT] Server will be shut down in $minLeft minutes"
python3 $discordScript $botToken $channelID "Servern kommer stängas ner om " $minLeft "minuter."
secLeft=$(($secLeft - 60))
sleep 60
done
python3 $discordScript $botToken $channelID "Servern stängs nu ner."
else
echo "[$(date +"%T")][ERROR] No Discord botToken or channelID found"
fi
fi
echo "[$(date +"%T")][SUCCESS] Existing PIDs: $pid"
exec kill -SIGINT $pid
isServerDown=$(ps axf | grep ConanSandboxServer-Win64-Test.exe | grep -v grep)
cpt=0
while [ ! -z "$isServerDown" ]; do
echo "[$(date +"%T")][WAIT] Server is stopping..."
((cpt++))
sleep 1
isServerDown=$(ps axf | grep ConanSandboxServer-Win64-Test.exe | grep -v grep)
done
echo "[$(date +"%T")][SUCCESS] Server stopped in $cpt seconds"
if [ "$discordBotEnable" = true ]; then
echo "[$(date +"%T")][SUCCESS] Discord bot is enabled"
if [ -n "$botToken" ] && [ -n "$channelID" ]; then
python3 $discordScript $botToken $channelID "Servern stängdes ner efter $cpt sekunder."
else
echo "[$(date +"%T")][ERROR] No Discord botToken or channelID found"

exec
更换外壳使用给定的命令,如exec()
系统调用。当命令(kill
此处的 )停止时,shell 不再存在,因此脚本无法继续。
两种例外情况是 1) 当exec
给出重定向时,在这种情况下它仅将它们应用到当前 shell 中,以及 2) 当命令无法执行时,在这种情况下exec
会给出错误并返回错误的退出代码。
所以,exec kill ...
几乎与 相同kill ... ; exit
。不完全相同,但在本例中足够接近。
