脚本技巧

截断日志，保存最后10行

echo "$(tail -n 10 filename.log)" > filename.log

监控日志，执行特定命令

tail -fn0 /root/.klei/DoNotStarveTogether/Cluster_1/Master/server_log.txt | \

while read line ; do

echo "$line" | grep "Sim paused"

if [ $? = 0 ]

then

#  cpulimit -e dontstarve_dedicated_server_nullrenderer -l 7 -b

echo "$line"

curl https://*?text=世界暂停了 2>/dev/null

fi

echo "$line" | grep "Sim unpaused"

if [ $? = 0 ]

then

#  curl https://*text=世界恢复了

echo "世界恢复正常了["`date`"]"

fi

echo "$line" | grep "Client authenticated:"

if [ $? = 0 ]

then

url="https://*"

curl \

--data-urlencode "text=玩家进入世界" \

--data-urlencode "desp=$line" \

$url 2>/dev/null

fi

done
