China DOS Union

May I ask the experts:
1. How to change the attributes of all subdirectories under DOS?
2. Is it possible to require the user to enter a password to continue execution during the execution of a batch file?

ATTRIB is sufficient, for example:
ATTRIB +S C:\DOS

To use passwords in batch files, some batch enhancement tools can be used, such as STRINGS, WBAT, etc.

Can I use attrib to set all subdirectories in a certain directory to hidden attributes at once? There are so many DOS software on the webmaster's website, I really don't know where to start! For a beginner, where should I start learning?

For wildcard folder (directory) names, the built-in ATTRIB in MS-DOS can't do it, but the ATTRIB command in my MS-DOS 7.10 boot disk with the /D parameter can:

For learning DOS, communicating with everyone is the best way to learn, and we can progress together.

In the future, I will definitely have many more questions to ask. Moderator, don't be afraid of being troubled! If there's a chance, I will definitely invite you for tea. Please be so kind as to accept!

Okay, welcome to ask questions!

I accidentally saw an article saying that just adding in the batch file:
@echo off
choice /c:（password）/n is equivalent to putting a lock on the running of the batch file. I wonder what the principle is? Will this method be cracked by others?

This password setting can naturally be easily cracked, just press the Ctrl+Break key.

This time I don't agree with the moderator's statement!
The syntax of using choice /cpassword)/n is set to prevent others from running this batch file. But you said that pressing Ctrl+Break key can easily crack it. Let's ask: Can you continue to run this batch file after pressing it? No! The function of pressing Ctrl+Break key is to terminate the operation, not to skip the password and continue running! This means that you can't run my batch file without entering the correct password!
Haha, if the moderator doesn't come up with other methods, then I win this first round!

You can modify your batch script, the person above.

That's right!
I can only modify the registry to prohibit running all programs. Please refer to my post "One-click Lock Computer Using Batch File": http://www2.zzu.edu.cn/ie/newdos/dispbbs.asp?boardID=12&ID=1814

It is running under DOS, see my reply here:

What you said is not right either. You can experiment with each key on the keyboard one by one. I've experimented because that password can only be a combination of one or more, and as long as you press the right letter, you can continue running. It's completely scaring people—just scares kids, no use for experts! You can go try it! It's just a paper tiger!
