线上脚本内容如下：
[[email protected] ~]# cat /data/scripts/check_php.sh

#!/bin/bash Date=`date "+%Y-%m-%d %H:%M:%S"` Num=$(ps -ef|egrep "countjs_syc_site*|countjs_syc_plan*|countjs_syc.php|countjs_syc_img*|setcache*"|grep -v grep |wc -l) Pid=$(/bin/ps -ef|egrep "countjs_syc_site*|countjs_syc_plan*|countjs_syc.php|countjs_syc_img*|setcache*"|grep -v grep| awk ‘{print $2}‘) if [ $Num -eq 0 ];then echo "$Date No Process" >> /data/scripts/check_php.log else for i in $Pid do echo "$Date Running Process $i" >> /data/scripts/check_php.log ##define Get Seconds var Sec=$(ps -p $i h -o etime|tail -1|awk ‘BEGIN { FS = ":" }{if (NF == 2) {print $1*60 + $2 } else if (NF == 3) {split($1, a, "-");if (a[2] != "" ) {print ((a[1]*24+a[2])*60 + $2) * 60 + $3; } else {print ($1*60 + $2) * 60 + $3;}}}‘) if [ $Sec -ge 1800 ];then echo $Date >> /data/scripts/check_php.log ps -ef | grep $i | grep -v grep >> /data/scripts/check_php.log kill -9 $i echo "$Date $i The process runs for more than 30 minutes,The process has been killed." >> /data/scripts/check_php.log else echo "$Date $i The process runs in less than 30 minutes" >> /data/scripts/check_php.log fi done fi echo ‘===========================‘ >> /data/scripts/check_php.log

另外一种脚本形式如下：
cat /root/scripts.awk

#!/usr/bin/awk -f BEGIN { FS = ":" } { if (NF == 2) { print $1*60 + $2 } else if (NF == 3) { split($1, a, "-"); if (a[2] != "" ) { print ((a[1]*24+a[2])*60 + $2) * 60 + $3; } else { print ($1*60 + $2) * 60 + $3; } } }

脚本分析如下：

ps -ef|grep 18020 |grep -v grep|awk ‘{print $2}‘; ps -p 18020 h -o etime|tail -1|awk ‘BEGIN { FS = ":" }{if (NF == 3) {split($1, a, "-");if (a[2] != "" ) {print ((a[1]*24+a[2])*60 + $2) * 60 + $3; } else {print ($1*60 + $2) * 60 + $3;}}}‘ echo " 03:19:15"|awk ‘BEGIN { FS = ":" }{if (NF == 3) {split($0, a, ":");if (a[1] != "" ){print a[1],a[2] }}}‘ echo " 03:19:15"|awk ‘BEGIN { FS = ":" }{if (NF == 3) {split($0, a, ":");if (a[1] != "" ){print a[1],a[3] }}}‘ ps -p 18020 -o etime|tail -1|awk ‘BEGIN { FS = ":" }{if (NF == 3) {split($0, a, ":");if (a[2] != "" ) {print a[1],a[2],a[3] };{print ($1*60 + $2) * 60 + $3;}}}‘ 03 54 06 14046

awk 字符串处理函数,split

split(s,a,fs) 以fs为分割符 将s字符串分成序列a split可以实现对字符串进行数组类型的分割，下面用例子来说明下。 [[email protected] ~]# echo ‘abcd‘?| awk ‘{len=split($0,a,"");for(i=1;i<=len;i++)print "a["i"]="a[i];print "length="len}‘ a[1]=a a[2]=b a[3]=c a[4]=d a[5]=? length=5

解析说明：首先把abcd换为一个数组，并且数组的分隔符为没有符号，len=split($0,a,"")为获取了整个数组的长度，，之后进行输出。在awk中如果是当做字符串输出的字符，全部用双引号来引起来。

查看php脚本运行的时间：

[[email protected] ~]# ps -p 5493 h -o etime 1-01:35:00 运行了1天1小时35分00秒 根据进程号过滤出具体的运行脚本名称： [[email protected] ~]# ps -ef|grep 5493|grep -v grep root 5493 5490 0 9月18 ? 00:00:00 /bin/bash /data/cron/chksh/setcache.sh root 5506 5493 0 9月18 ? 00:00:00 /usr/bin/php /data/cron/ptask/setcache.php [[email protected] ~]# ps -p 5493 h -o etime|tail -1 1-01:40:58 [[email protected] ~]# ps -p 5493 h -o etime|tail -1|awk ‘BEGIN { FS = ":" }{if (NF == 3) {split($1, a, "-");if (a[2] != "" ) {print a[1],a[2],a[3]}}}‘ 1 01

计算进程运行的分钟数：

[[email protected] ~]# ps -p 5493 h -o etime|tail -1 1-01:47:56 [[email protected] ~]# ps -p 5493 h -o etime|tail -1|awk ‘BEGIN { FS = ":" }{if (NF == 3) {split($1, a, "-");if (a[2] != "" ) {print ((a[1]*24+a[2])*60 + $2)}}}‘ 1547 计算进程运行的秒数： [[email protected] ~]# ps -p 5493 h -o etime|tail -1|awk ‘BEGIN { FS = ":" }{if (NF == 3) {split($1, a, "-");if (a[2] != "" ) {print ((a[1]*24+a[2])*60 + $2)*60 + $3}}}‘ 93036

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

[[email protected] ~]# ps -p33920 h -o etime 04:31:49 [[email protected] ~]# ps -p33920 h -o etime|awk ‘BEGIN { FS = ":" }{if (NF == 3) {split($1, a, "-");if (a[2] != "" ) {print a[1]}}}‘ [[email protected] ~]# ps -p33920 h -o etime|awk ‘BEGIN { FS = ":" }{if (NF == 3) {split($1, a, "-");if (a[2] != "" ) {print a[2]}}}‘ [[email protected] ~]# ps -p33920 h -o etime|awk ‘BEGIN { FS = ":" }{if (NF == 3) {split($1, a, "-");if (a[2] != "" ) {print $2 }}}‘ [[email protected] ~]# ps -p33920 h -o etime|awk ‘BEGIN { FS = ":" }{if (NF == 3) {split($1, a, "-");if (a[2] != "" ) {print $3 }}}‘ 此时数值都为空

所以此时采用下面的公式计算秒数也为空：

ps -p33920 h -o etime|awk ‘BEGIN { FS = ":" }{if (NF == 3) {split($1, a, "-");if (a[2] != "" ) {print ((a[1]*24+a[2])*60 + $2)*60 + $3}}}‘
