shell总结

启动jar包脚本

#!/bin/sh
nohup java -jar  ./overseasNews.jar > /dev/null 2>&1 &
echo `jps | grep overseasNews.jar | grep -v grep ` " started!!!"

启动脚本2

#!/bin/bash
mypath=.
mainclass=com.isi.JdbcTest
for f in lib/*.jar
do
        mypath=$mypath:$f
done

java -Xmx2g -cp $mypath $mainclass

停止指定线程脚本

#!/bin/sh
info=`ps -ef|grep  overseasNews.jar  |grep -v grep`
echo "killing thread info ####### " $info
pid=`echo $info |awk '{print $2}' `
kill -9 $pid
echo "pid " $pid " ##### killed!!!!"

停止线程脚本

kill -9 `ps -ef|grep harm_mirror_crawler.jar | grep -v grep|awk '{print $2}'`

两个脚本合并，通过输入参数控制启动和停止

#!/bin/sh
 if [ $# = 1 ] && [ $1 = "start" ] ; then
   nohup java -jar  ./overseasNews.jar > /dev/null 2>&1 &
   echo `jps | grep overseasNews.jar | grep -v grep ` " started!!!"
 elif [ $# = 1 ] && [ $1 = "stop" ] ; then
   info=`ps -ef|grep  overseasNews.jar  |grep -v grep`
   echo "killing thread info ####### " $info
   pid=`echo $info |awk '{print $2}' `
   kill -9 $pid
   echo "pid " $pid " ##### killed!!!!"
 else
  echo " arg error the only argument is start/stop" 
 fi

递归删除

find  .  -name  '*.exe'  -type  f  -print  -exec  rm  -rf  {} \;

查看端口是否通

wget 192.167.1.1:2233

循环请求

#!/bin/bash
for ((i=1; i<=127; i ++))  
do  
    curl is ""
    sleep 4s
done 

压缩与解压

tar -cvf test.zip test
tar -zxvf test.zip

批量启动

#!/bin/bash
dir=`pwd`
server=`ls -d *server*`
echo "server path is "$dir/$server
cd $dir/$server
sh ./sbin/start.sh
echo "server is starting wait for 10 s"
sleep 10s 
cd $dir
for i in `ls  -d  client*`
do 
  cd $dir/$i
  echo "client path is==>"  $dir/$i                                                                                                                                                                              
  sh ./sbin/start.sh
  sleep 1s
done

批量清空

for i in `find . -name "*.out"`; do cat /dev/null >$i; done

find  .  -name  '*log'  -type  f  -print  -exec   truncate -s 0 {} \;   

批量删除

find  .  -name  '*.log'  -type  f  -print  -exec  rm  -rf  {} \;

for i in `find . -name "*.out"`; rm -rf >$i; done

注意:如果使用for循环的批量删除和清空,磁盘空间如果满了,就会报 No space left on device,使用find的 -exec就不会

监控日志,重启卡死程序

#!/bin/bash
dir=`pwd`
while true
do
cd $dir
for i in `ls  -d  client*/`
do 
  cd $dir/$i
  echo "client path is==>"  $dir/$i
  size=`cat $dir/$i/nohup.out | wc -l`
  if [ $size == 0 ] 
  then
    sh ./sbin/stop-client.sh                                                                                                                                                                                     
    sh ./sbin/start-client.sh
    echo "size is 0 restart client!!!"
  else
    echo "logsize="$size
  fi
done
 echo "scan over sleep 1 min!!!!"
 sleep 60s
done
