Delete certain lines in a txt file via a batch file
提问by chrome
I have a generated txt file. This file has certain lines that are superfluous, and need to be removed. Each line that requires removal has one of two string in the line; "ERROR" or "REFERENCE". These tokens may appear anywhere in the line. I would like to delete these lines, while retaining all other lines.
我有一个生成的txt文件。这个文件有一些多余的行，需要删除。每行需要删除的行中有两个字符串之一；“错误”或“参考”。这些标记可能出现在行中的任何位置。我想删除这些行，同时保留所有其他行。
So, if the txt file looks like this:
因此，如果 txt 文件如下所示：
Good Line of data bad line of C:\Directory\ERROR\myFile.dll Another good line of data bad line: REFERENCE Good line
I would like the file to end up like this:
我希望文件最终是这样的：
Good Line of data Another good line of data Good line
TIA.
TIA。

Use the following:
使用以下内容：
type file.txt | findstr /v ERROR | findstr /v REFERENCE
This has the advantage of using standard tools in the Windows OS, rather than having to find and install sed/awk/perl and such.
这具有在 Windows 操作系统中使用标准工具的优点，而不必查找和安装 sed/awk/perl 等。
See the following transcript for it in operation:
请参阅以下文字记录以了解它的运行情况：
C:\>type file.txt Good Line of data bad line of C:\Directory\ERROR\myFile.dll Another good line of data bad line: REFERENCE Good line C:\>type file.txt | findstr /v ERROR | findstr /v REFERENCE Good Line of data Another good line of data Good line

You can accomplish the same solution as @paxdiablo's using just findstr by itself. There's no need to pipe multiple commands together:
您可以单独使用 findstr 来完成与@paxdiablo 相同的解决方案。无需将多个命令通过管道连接在一起：
findstr /V "ERROR REFERENCE" infile.txt > outfile.txt
Details of how this works:
这是如何工作的详细信息：
- /v finds lines that don't match the search string (same switch @paxdiablo uses)
- if the search string is in quotes, it performs an OR search, using each word (separator is a space)
- findstr can take an input file, you don't need to feed it the text using the "type" command
- "> outfile.txt" will send the results to the file outfile.txt instead printing them to your console. (Note that it will overwrite the file if it exists. Use ">> outfile.txt" instead if you want to append.)
- You might also consider adding the /i switch to do a case-insensitive match.
- /v 查找与搜索字符串不匹配的行（@paxdiablo 使用的相同开关）
- 如果搜索字符串在引号中，则使用每个单词执行 OR 搜索（分隔符为空格）
- findstr 可以接受一个输入文件，您不需要使用“type”命令为其提供文本
- ">outfile.txt" 会将结果发送到文件 outfile.txt 而不是将它们打印到您的控制台。（请注意，如果文件存在，它将覆盖文件。如果要追加，请改用“>> outfile.txt”。）
- 您还可以考虑添加 /i 开关来进行不区分大小写的匹配。

If you have sed:
如果你有 sed：
sed -e '/REFERENCE/d' -e '/ERROR/d' [FILENAME]
Where FILENAMEis the name of the text file with the good & bad lines
FILENAME带有好行和坏行的文本文件的名称在哪里

If you have perl installed, then perl -i -n -e"print unless m{(ERROR|REFERENCE)}"should do the trick.
如果您安装了 perl，那么perl -i -n -e"print unless m{(ERROR|REFERENCE)}"应该可以解决问题。
