Hi,

How can I check the mysql connection for a user/password using batch/shell script?

I've user name and password, and I need to authenticate whether they are correct or not, but how?

I tried this way:

I've created a batch file "run.bat" with "mysql -u User--password=UserPassword < commands.sql"
"commands.sql" file contains "\q"
When I run the file "run.bat" the output is nothing when User/Password are correct and "ERROR 1045 (28000): Access denied for user ... " when User/Password are incorrect. Now can we capture this output, and decide whether the connection is successful or not, if yes how?

Regards
