【1.7】shell读取文件，逐行读取

直接上案例：

while read line
do
table_name=`echo $line | awk '{print $1}'`
echo $table_name
echo "Start running SQL script for DB "$table_name" at "$(date +%Y-%m-%d%t%A%t%T) >> $logfile
mysql  -pbfgame20 <<EOF
use log_db;
alter table log_db.$table_name drop partition p$PARTNAME4,p99;
alter table log_db.$table_name add partition(partition p$NOWNAME VALUES LESS THAN (to_days('$NOW_MONTHS')) ENGINE = InnoDB);
alter table log_db.$table_name add partition(partition p99 VALUES LESS THAN MAXVALUE ENGINE = InnoDB);

EOF
