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;}}}‘

14046awk 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。

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}}}‘然而采用下面的公式来计算是正确的:
[[email protected] ~]# 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} else {print ($1*60 + $2) * 60 + $3;}}}‘
