请告知如何使用 select 语句结果作为变量并将其进一步传递给脚本。简单的脚本:
#!/bin/sh
# --mysql part START--
pwd="pass"
D="db"
mysql -uuser -p$pwd -D$D -s -N -e "SELECT port FROM table where username='$1';"
/usr/bin/mysql -uroot -p$pwd -D$D<< eof
eof
port=$(mysql Select) # declaring select result as a variable , probably wrong
echo "port $port;" >> /tmp/blabla.txt # <- this part is not working
请指教。提前致谢
