shell脚本形式获取pid、进程重启等

本文介绍: example on e:#!/bin/bash x pid=$(ps –e f |grep “python” | grep –v “g re p” | awk ‘{print $2}’) #注意“=”号前后无空格 echo $xpid f o r xx pid in $xpi dd o echo “xx p id=$xx p id“done或者#!/bin/bashxp id=`ps -ef |g re p “python” | g re p –v “g rep” | awk ‘{print $2}’` #最外面的两个是反

example one:获取进程名为“python“的进程 pi d值

#!/bin/bash
xpid=$(ps -ef |grep "python" | grep -v "grep" | awk '{print $2}') #注意"="号前后无空格；右侧命令执行后的输出值赋值给变量xpid
echo "进程号：$xpid"
for xxpid in $xpid
do
echo "遍历显示：xxpid=$xxpid"
done

或者

#!/bin/bash
xpid=`ps -ef |grep "python" | grep -v "grep" | awk '{print $2}'` #最外面的两个是反单引号`与~在同个按键上，不是单引号'哦
echo "进程号：$xpid"
for xxpid in $xpid
do
echo "遍历显示：xxpid=$xxpid"
done

重启 jar包

#!/bin/bash
xpid=`ps -ef |grep "xxx.jar" | grep -v "grep" | awk '{print $2}'`
echo $xpid
for xxpid in $xpid
do
kill -9 $xxpid #先关停xxx.jar应用
done
sleep 1
nohup java -jar xxx.jar &gt;outlog.log 2&gt;&amp;1 &amp;  #再启动xxx.jar应用
newpid=`ps -ef |grep "xxx.jar" | grep -v "grep" | awk '{print $2}'`
if[ $newpid ];then #注意if[空格+条件+空格],条件语句与[]之间前后都一定要有空格
 echo "newpid=$newpid"
else
 echo "newpid is null"
