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
