问题描述

我知道有一些方法重定向过程中运行bash命令,但我不知道它是怎么做的究竟

I know there's some way to run bash command during redirect, but I don't know how exactly it is done.

我想要做这样的事情:

#!/bin/bash
mysql -uUser -pPasswd << EOF
echo 'I wanna echo something by using echo which is run by bash'
use Mydb
some sql commands here
commit;
EOF

我做过的错误使用中的&LT;&LT; EOF,但没做,现在。

I had ever done that by mistake by using " in the "<< EOF" , but failed to make it now.

推荐答案

您可以使用的:

You can use system command from within the mysql command line client:

#!/bin/bash
mysql -uUser -pPasswd << EOF
system echo 'I wanna echo something by using echo which is run by bash';
use Mydb
some sql commands here
commit;
EOF
