脚本一:

#!/bin/sh

program=XXXX #进程名

sn=`ps -ef | grep $program | grep -v grep |awk '{print $2}'` #获得进程端口号

if [ "${sn}" = "" ] #如果为空,表示进程未启动

then

nohup /home/oracle/XXXX & #后台启动进程

echo start ok !

else

echo running

fi

脚本二:

#!/bin/sh

ps -ef |grep ./FileServer > /dev/null 2>&1 #检测进程写入/dev/null

if [ $? -eq 0 ] #0为正常

then

echo logprocess run ok!

else

nohup /home/oracle/XXXX &

echo start ok !

fi

脚本三:

#!/bin/sh

count=`ps -fe |grep "a.out" | grep -v "grep" | wc -l`

if [ $count -lt 1 ]; then

/root/sh/restart.sh

脚本四:

PNAME="authd"

PATHNAME=/root/cauthd/build/

LENGTH=`ps -ef|grep "$PNAME"|grep -v grep|cut -b 49-200|wc -c `

if test $LENGTH -eq 0

then

cd $PATHNAME

nohup $PNAME >/dev/null

脚本五:

#! /bin/bash

echo "请输入进程名:"

read process

echo "你要查找的进程是 $process ,正在查找..."

ps > text1

grep "$process" text1

declare -i a=$?

if [ $a -eq 0 ]

then

echo "该进程存在"

else

echo "该进程不存在"

fi

rm text1

检测进程 cpu mem

[root@test ~]# ps aux |awk -v OFS="\t" 'BEGIN{print "httpd"}/%MEM|httpd/{print $3,$4}'
