假设/var/log/a.log是某程序的log文件 内容形如：2012-07-27 18:12:17,788 INFO [com.kmsocial.search.websearch.WeiboPool:229] - Weibo pool running! 要求写个脚本，如果超过2分钟没有产生新log则发送邮件给admin@localhost.localdomain。 代码如下: #!/bin/bash LOGFILE="/var/log/a.log" STARTNUM=`wc -l $LOGFILE` mail_to_root(){ mail -s "weibo pool has some problem" root<<! there has no logs in two ! } exec 6<"$LOGFILE" while : do NEWNUM=`wc -l $LOGFILE` if [ "$STARTNUM"_ = "$NEWNUM"_ ];then mail_to_root else STARTNUM=$NEWNUM fi while read -u 6 new_log do if echo "$new_log" | grep -q "Weibo pool running";then while read -u 6 tmp do : done break else mail_to_root fi done sleep 120 done exec 6<&- (责任编辑：IT) |
