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. [ Last edited by NaturalJ0 on 2006-8-15 at 16:22 ]

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.

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

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

[ Last edited by wang6610 on 2006-9-1 at 15:44 ] Change echo set username=%%0 >username.bat to echo (set username=%%0)>username.bat or >username.bat echo set username=%%0 [ Last edited by namejm on 2006-11-5 at 12:21 PM ]
