Windows: in batch file, write multiple lines to text file?
提问by user1686
How can I do the following in a Windows batch file?
如何在 Windows 批处理文件中执行以下操作？
- Write to a file called subdir/localsettings.py
- Overwrite all existing content...
- ...with multiple lines of text...
- ...including a string that is "[current working directory]/subdir" (which I think might be
%cd%/subdir?)
- 写入名为 subdir/localsettings.py 的文件
- 覆盖所有现有内容...
- ...带有多行文本...
- ...包括一个字符串“[当前工作目录]/subdir”（我认为可能是
%cd%/subdir？）
Please note, I want to do this as part of a batch script so I can't use con+ Enter (at least, maybe I can, but I don't know how to simulate Enter as part of a batch script).
请注意，我想将此作为批处理脚本的一部分来执行，因此我不能使用con+ Enter（至少，也许我可以，但我不知道如何将 Enter 作为批处理脚本的一部分进行模拟）。
Thanks!
谢谢！

Use output redirection >and >>
使用输出重定向>和>>
echo one>%file%
echo two>>%file%
echo three>>%file%
Or in a more readable way: (In cmd.exe, using "echo one >%file%" would include the whitespace before >.)
或者以更易读的方式：（在 中cmd.exe，使用“ echo one >%file%”将包括 之前的空格>。）
>%file% echo one
>>%file% echo two
>>%file% echo three
You could also use:
您还可以使用：
(
echo one
echo two
echo three
) >%file%
回答by access_granted
echo Line 1^
Line 2^
Line 3 >textfile.txt
Note the double new-lines to force the output:
请注意强制输出的双换行符：
Line1
Line2
Line3
Also:
还：
(echo Line 1^
Line 2^
Line 3)>textfile.txt
