time=`date  +%G%I%d%H%M` #年月日时分

db=products
echo "#产品库" >/sqlbak/${db}_$time.sql  #备份文件名为[库名_年月日时分.sql]
mysqldump --add-drop-table -c  --allow-keywords --force --password=1234567890 --user=root $db >>/sqlbak/${db}_$time.sql

db=news   #另一个库

echo "#新闻库" >/sqlbak/${db}_$time.sql
mysqldump --add-drop-table -c  --allow-keywords --force --password=1234567890 --user=root $db |bzip2 -9 >/sqlbak/${db}_$time.sql.bz2

#--add-drop-table是添加一个删出命令。
#-c是完整插入,每行插入都包括字段名
#--force是出错也继续
#--allow-keywords是对于保留字做字段名时对字段名加反引号。
