emailFile='/tmp/email.txt'

echo $(date +%Y-%m-%d' '%H:%M:%S) >> $emailFile

#backup DCOM library
$command --login-path=backtest --add-locks -q DCOM > $back_path/$back_Dir.sql

2.备份有数据的表（只是备份数据不包含表结构）
#!/bin/bash
path=/opt/sql
dir=mkdir $path/$(date +%Y-%m-%d)
dir1=$(date +%Y-%m-%d)
mysql --login-path=backtest -e "show tables from DCOM" > $path/$dir1/tables.txt

for i in cat $path/$dir1/tables.txt
do
number=mysql --login-path=backtest -e "select count(*) from DCOM.$i" | tail -1
if [ $number -gt 0 ]
then echo "$i" >> $path/$dir1/datanum.txt
else echo "$i" >> $path/$dir1/nodatanum.txt
fi
done

for tables in cat $path/$dir1/datanum.txt
do
mysqldump --login-path=backtest --add-locks -q -t DCOM $tables > $path/$dir1/$tables.sql
done

rm -f $path/$dir1/{datanum.txt,nodatanum.txt,tables.txt}
