It is suggested to ask questions in the batch processing room next time

Is this okay?

echo open 192.168.0.13>ftp.txt

echo 123>>ftp.txt

echo 123 >>ftp.txt

echo cd wwwroot>>ftp.txt

echo put c:\%你的变量%.txt>>ftp.txt

echo bye>>ftp.txt



ftp -s:ftp.txt

Note that I added an extra space after the password; if there's no space, it will get stuck there.

```
@echo off
set /p ravel=Please enter the file to upload:
set "ravel=%ravel:"=%"
>ftp.txt echo open 192.168.0.13
>>ftp.txt echo 123
>>ftp.txt echo 123
>>ftp.txt echo cd wwwroot
>>ftp.txt echo put "%ravel%"
>>ftp.txt echo bye
start ftp -v -i -s:"%ftpFile%"
```

set "ravel=%ravel:"=%"

Does the HAT moderator mean that this sentence refers to using the set command to remove the spaces in the variable ravel?
I saw in set /? that there is such a passage:

Environment variable substitution has been enhanced as follows:

%PATH:str1=str2%

This will expand the PATH environment variable, replacing each "str1" in the expanded result with "str2"
To effectively remove all "str1" from the expanded result, "str2" can be empty.

Then what is the effect of "str2 can be empty."? I tested it, and the variable doesn't seem to change?

The landlord means to delete the double quotes that the user may input to avoid causing errors in the subsequent commands.
