Linux下的进程PID捕捉过程(简便的进程检查脚本)

以下两个脚本我分别用SHELL和PYTHON编写，功能相同。

SHELL

 

#!/bin/sh



P_1=”nginx”

P_2=”mysqld_safe”



#获取进程ID方法

processIDget(){

process=(`ps –ef |grep –i “$1” |grep –v grep |awk ‘{print $2}’`)



if [ “${process[*]}” != “” ]

then

       num=${#process[*]}

       for ((i=0;i<$num;i++))

       do

       echo –ne “$1(${process[$i]}\t))”

       done

       echo

else

       echo –e ne “$1(服务未启)\t”

       echo

fi

}



#开始获取进程ID

echo –e “192.168.0.1(该有1个$P_1,$P2进程)”

processIDget $P_1

processIDget $P_2

 

 

 

 

 

PYTHON

 

#!/usr/bin/env python

# -*- coding:iso-8859-15 -*-



import os



P_1 = “nginx”

P_2 = mysqld_safe”

P = []

p.append(P_1)

p.append(P_2)



print “192.168.0.1(该有1个%s,1个%s进程)”%(P_1,P_2)

for I in p:

       prcs = os.popen(“ps –ef |grep %s | grep –v”%i).readlines()

       if not prcs:

              print I + “：服务未启”

       else:

              for x in prcs:

                     pid = []

                     pid = x.strip(“\n”).strip().split()[1]

                     print I + “:” + “(” +pid + “)”
