将Bash脚本SSH导入MYSQL Server并创建带有破折号的数据库

Question

I keep having trouble with this command:

ssh -t $SSSSHUSER@$SSSSH "echo \"CREATE DATABASE \`$NEWDB\`; GRANT ALL ON \`$NEWDB\`.* TO '$SSMYSQLUSER'@'$SSMYSQLSERVER';\" | /usr/bin/mysql -u$SSMYSQLUSER -p$SSMYSQLPWD ;"

Even tho I escaped the backticks the database creation fails when a - is present in the database name. Any ideas how to fix the syntax?

When running this locally everything works:

echo "CREATE DATABASE \`$NEWDB\`; GRANT ALL ON \`$NEWDB\`.* TO '$MYSQLUSER'@'localhost';" | /Applications/MAMP/Library/bin/mysql -u"$MYSQLUSER" -p"$MYSQLPWD"

Thanks

使用set -x进行调试后，此代码可以正常工作：

ssh -t $SSSSHUSER@$SSSSH "echo 'CREATE DATABASE \`$NEWDB\`; GRANT ALL ON \`$NEWDB\`.* TO $SSMYSQLUSER@$SSMYSQLSERVER;' | /usr/bin/mysql -u$SSMYSQLUSER -p$SSMYSQLPWD ; "
