China DOS Union

What command is used to create a file? I'm asking for advice.

In DOS, the command to create a directory is the `md` command. You must be asking if there is a command used to create a file, just like the function of creating a new text file (or a new Word file) in Windows. Well, actually, there isn't such a command in DOS. But there are many ways to create a new file in DOS. For example, you can copy another file over (using `copy`), or you can use the Edit command to edit a file and then save it, or you can use the pipe method like `dir > newfile.ext` to create a file. In short, in DOS, to create a new file, you need to determine the content of the file first (even if it's empty), and then you can save it as a file. This is different from Windows. In Windows, you can first create an empty file and then enter content, but in DOS, you have content first and then the file.

That's the meaning. I got inspiration after reading it. Thanks. Also, I would like to ask: Can you edit any file, such as EXE, BAT, TXT, etc. by COPY, and then save it as the file type you need, like saving an EXE as TXT?

This doesn't work. The file name is just an identifier. What type this file actually is depends on the content of the file itself. Just like a person's name, no matter how you change the name, the person's attributes don't change at all.

Files are divided into two types: text files and binary files. Text files can be copied over and then edited with Edit, but although binary files can be opened with Edit, the content is all garbled and cannot be edited in principle. As the person upstairs said, filenames are named by the people operating the computer, but the content of the file does not change with the change of the filename. We need to give appropriate names to files according to their content, but we cannot imagine that the content of the file changes with the change of the name.

Thanks. I mean, for example, if you want to create a text file, COPY an EXE file, delete all its contents, and enter text, then is it just a text file? If you want to create a HELP file by yourself, how to create it? Because my 98 boot disk doesn't have this file, and there's no such type. How to operate the dir > newfile.ext pipeline to create a file, and how to define the file type, can you explain it?

In principle, it can be like this, but there is absolutely no need to be so troublesome. Just use Edit to enter the content of the text file you want to create and then save it. It's just like directly using Notepad to enter the file content and then save it. Regarding pipeline operations, it is recommended that you study the basic knowledge of DOS carefully.

Got it, thank you very much!

There are many kinds.
1.------------------------------------
cd.>c:\New 1.txt
rem.>c:\New 1.txt
type nul>c:\New 1.txt

2.------------------------------------
c:>c:\New 1.txt

3.------------------------------------
copy nul c:\New 1.txt
echo. >c:\New 1.txt

The ones listed in 1 are relatively perfect. The ones in 2 and 3 occasionally produce blank lines or garbled codes. The ones that frequently produce text and garbled codes in the newly created files are not listed here. Please choose freely.
