Shell脚本:执行2个命令并保持第一个运行

我正在尝试为docker图像编写shell脚本,其中:

1. mssqql服务器已启动
2. 发生数据库设置

但是,使用当前脚本,数据导入完成后,sql server实例就会停止。有人能指出我做错了什么吗?

#!/bin/bash
database=myDB
wait_time=30s
password=myPw

exec /opt/mssql/bin/sqlservr &
echo importing data will start in $wait_time...
sleep $wait_time
echo importing data...

/opt/mssql-tools/bin/sqlcmd -S 0.0.0.0 -U sa -P $password -i ./init.sql

for entry in "table/*.sql"
do
  echo executing $entry
  /opt/mssql-tools/bin/sqlcmd -S 0.0.0.0 -U sa -P $password -i $entry
done

for entry in "data/*.csv"
do
  shortname=$(echo $entry | cut -f 1 -d '.' | cut -f 2 -d '/')
  tableName=$database.dbo.$shortname
  echo importing $tableName from $entry
  /opt/mssql-tools/bin/bcp $tableName in $entry -c -t',' -F 2 -S 0.0.0.0 -U sa -P $password
done
