China DOS Union

I've gone through some forum posts and found that FOR in pure DOS is not sufficient in functionality. Some experts mentioned using third-party software or other methods. Could you provide me with a third-party software and a simple usage method? Thanks a lot.

It is suggested to search the forum first. It seems there are many introductions. You can use programs like LMOD, strings, etc.

Can you read file content into a variable without using third - party tools?

What is the content of your file?

It is suggested to make a small tool by yourself with TC. It can be realized with just a dozen of lines of code.

What I did later was exactly like this.

Post the content of your txt file. If you want to use something as a variable, give me the batch processing without using third-party software

username
password

Just these two lines, how to write the batch script?


Thanks!

Okay.
I originally wanted a password function, and I wrote one myself with TC, here it is.
http://zhenlove.com.cn/cndos/fileup/files/PASSWORD.rar
Inside is PASSWORD.EXE
When running, it looks for PASSWORD.TXT in the same directory and reads its content as the original password.
When reading, it reads from the beginning of the file to the first carriage return, and there can be spaces and symbols before the carriage return.
Then it asks the user to enter the password to compare with the original password.
If they are the same, a PASSWORD.OK file is generated in the same directory.
If they are different, a PASSWORD.ERR file is generated in the same directory.
Both of these situations are normal operations, and a PASSWORD.RUN file will be generated in both cases. If the user presses Ctrl + C to forcefully interrupt, this file will not be generated.

When using it, you can use echo "Your Password">PASSWORD.TXT in the BAT to set the original password.
Then judge and handle according to the generation of the three status files. When using continuously, you need to delete the status indicator files yourself.

What is the name of the DOS variable to which PASSWORD.EXE assigns the read string?

PASSWORD.EXE is not assigned.
If you need to assign it, just assign it according to the status yourself.

namepass.txt
username
password


*.bat
echo set username=%%0 >username.bat
echo set password=%%0 > password.bat
find namepass.txt /i "username" >temp1.bat
find namepass.txt /i "password" >temp2.bat
call temp1.bat
call temp2.bat
del /q username.bat
del /q password.bat
del /q temp1.bat
del /q temp2.bat
echo %username% >>x.txt
echo %password% >>x.txt


I don't know if this expression is correct
If namepass.txt is as follows, then set should be changed to %%1
namepass.txt
username abc
password 123


If namepass.txt is as follows, colons are not allowed in the file name. I think there is a method in a certain post, probably echo !%name:~0,-1%_ !, which is to remove the colon and add a space, so that it can be changed to the same as the above one
namepass.txt
username:abc
password:123

namepass.txt

Thank you!

abc

123

There are two extra spaces after them. How to prevent them from being added? Thank you!

Change echo set username=%%0 >username.bat to echo (set username=%%0)>username.bat or >username.bat echo set username=%%0
