通过批处理文件删除 txt 文件中的某些行

我有一个生成的文本文件。这个文件中有一些行是多余的，需要删除。需要删除的每一行都有两个字符串中的一个: “ ERROR”或“ REFERENCE”。这些标记可以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。

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

我希望文件的结局是这样的:

Good Line of data
Another good line of data
Good line

TIA.

If you have sed:

sed -e '/REFERENCE/d' -e '/ERROR/d' [FILENAME]

Where FILENAME is the name of the text file with the good & bad lines

If you have perl installed, then perl -i -n -e"print unless m{(ERROR|REFERENCE)}" should do the trick.

最佳答案

Use the following:

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.

See the following transcript for it in operation:

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:

findstr /V "ERROR REFERENCE" infile.txt > outfile.txt

Details of how this works:

  • /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.

It seems that using the FIND instead of the FINDSTR can support also unicode characters. e.g. type file.txt | find /v "Ω"
