How can I get a list of user accounts using the command line in MySQL?

Question

I'm using the MySQL command-line utility and can navigate through a database. Now I need to see a list of user accounts. How can I do this?

I'm using MySQL version 5.4.1.

Answer 1

I can get the password with this query

SELECT username, password enter code hereFROM mysql.user;

But the passwords are encrypted, what type of encryption is that and how to decrypt using dictionary attack which is best tool

Answer 2

To see your users, it would be to use the mysql database.

USE mysql;

And then make the select.

SELECT user,host FROM user;

Another option is to put the BD.Table.

For example :

SELECT user,host FROM mysql.user;

Answer 3

Log in to MySQL as root and type the following query:

select User from mysql.user;

+------+
| User |
+------+
| amon |
| root |
| root |
+------+

Answer 4

SELECT User FROM mysql.user;

Use the above query to get the MySQL users.

Answer 5

$>  mysql -u root -p -e 'Select user from mysql.user' > allUsersOnDatabase.txt

Executing this command on a Linux command line prompt will first ask for the password of MySQL root user. On providing the correct password it will print all the database users to the text file.

Answer 6

This displays the list of unique users:

SELECT DISTINCT User FROM mysql.user;

Answer 7

To avoid repetitions of users when they connect from a different origin:

select distinct User from mysql.user;

Answer 8

Peter and Jesse are correct, but just make sure you first select the "mysql" database.

use mysql;
select User from mysql.user;

That should do your trick.

Answer 9

Use this query:

SELECT User FROM mysql.user;

Which will output a table like this:

+-------+
| User  |
+-------+
| root  |
+-------+
| user2 |
+-------+

As Matthew Scharley points out in the comments on this answer, you can group by the User column if you'd only like to see unique usernames.

Answer 10

I found his one more useful as it provides additional information about DML and DDL privileges

SELECT user, Select_priv, Insert_priv , Update_priv, Delete_priv, 
       Create_priv, Drop_priv, Shutdown_priv, Create_user_priv 
FROM mysql.user;

Answer 11

MySQL stores the user information in its own database. The name of the database is MySQL. Inside that database, the user information is in a table, a dataset, named user. If you want to see what users are set up in the MySQL user table, run the following command:

SELECT User, Host FROM mysql.user;

+------------------+-----------+
| User             | Host      |
+------------------+-----------+
| root             | localhost |
| root             | demohost  |
| root             | 127.0.0.1 |
| debian-sys-maint | localhost |
|                  | %         |
+------------------+-----------+

Answer 12

I use this to sort the users, so the permitted hosts are more easy to spot:

mysql> SELECT User,Host FROM mysql.user ORDER BY User,Host;

Answer 13

The mysql.db table is possibly more important in determining user rights. I think an entry in it is created if you mention a table in the GRANT command. In my case the mysql.users table showed no permissions for a user when it obviously was able to connect and select, etc.

mysql> select * from mysql.db;
mysql> select * from db;
+---------------+-----------------+--------+-------------+-------------+-------------+--------
| Host          | Db              | User   | Select_priv | Insert_priv | Update_priv | Del...

Answer 14

A user account comprises the username and the host level access.

Therefore, this is the query that gives all user accounts

SELECT CONCAT(QUOTE(user),'@',QUOTE(host)) UserAccount FROM mysql.user;

Answer 15

I find this format the most useful as it includes the host field which is important in MySQL to distinguish between user records.

select User,Host from mysql.user;

Answer 16

SELECT * FROM mysql.user;

It's a big table so you might want to be more selective on what fields you choose.

Answer 17

If you are referring to the actual MySQL users, try:

select User from mysql.user;
