主要练习sed的部分高级语法和正则匹配，不过其实用perl语法更方便。主要sed语法如下
#处理pt-query工具分析后的mysql慢查询
#头部 尾部
#!/bin/bash
echo "used: sh chsqltohtml.sh abc.log,it will create abc.html to the current path"
SLOWLOG=$1
INDEXHTML=`echo $SLOWLOG|cut -d . -f 1`.html
echo $SLOWLOG
echo ${INDEXHTML}
sed -e '1 s/^$/<html>\n\t<head><meta charset="gbk" \/>\n<title>'$SLOWLOG'慢查询<\/title> \n\t<\/head>\n\t\t<body bgcolor="#87CEEB">\n\t\t<h3 style="color:green;font-size:40px;text-align:cen
