How to copy specified content into a specified file - China DOS Union Forum

Under Windows XP, if you want to copy all the text content after the third line of 1.txt to a specified text file, how can you achieve it?

```
for /f "skip=3 tokens=*" %%i in (1.txt) do @echo %%i >>指定文件.txt
```

Then how to get only a few lines? For example, if a text file has 100 lines, and now we only need lines 20 - 25 and the content after line 30, how to write it?

In addition, if you want the format of the extracted file content to be consistent with the original file format, for example, there are blank lines between lines 35 to 40, and the first line of lines with text all have spaces, how to achieve it?

It should be quite complicated to implement with batch processing, while it's much simpler with VBS.

Try Horst's Lmod program.

You can try to solve it with sed


sed -n "3,$p" 1.txt >temp.txt

Is it very complicated to achieve only through DOS batch processing without relying on third-party software?

Agree with the 4th floor.


with CreateObject("SAFRCFileDlg.Fileopen")
    .openfileopendlg
    if not len(trim(.filename)) = 0 then 
        oldfilename = .filename
    else 
        msgbox "No file selected!"
        wscript.quit
    end if
end with
newfilename = left(oldfilename,len(oldfilename) - 4) & "cxs" & right(oldfilename,4)
number1 = inputbox("Enter the starting line number:")
number2 = inputbox("Enter the number of lines:")
with createobject("scripting.filesystemobject")
    set rfile = .opentextfile(oldfilename,1,true)
    set wfile = .opentextfile(newfilename,2,true)
    for i = 1 to number1
        rfile.skipline
    next
    for j = 1 to number2
        str = rfile.readline
        wfile.writeline str
    next
end with

Save it as "File Processing.vbs" and then double-click to run, which can roughly meet your requirements. Of course, you can also write the code into a vbs file in the batch processing to achieve the effect of batch processing. In that case, you can remove the previous dialog box part and add parameters. Oh, I should have used adodb, but I forgot.
