How do I remove all the lines in a text file that are present in another text file in Windows?

问题

I have two files: content.txt and remove.txt. I would like to run .cmd script that removes all lines from content.txt that are in remove.txt. The result should go to result.txt.

For example:

content.txt

abc
1234
hello
qwerty

remove.txt

abc
hello
def

result.txt

1234
qwerty

This question is the same but using Perl: Removing lines in one file that are present in another file. I can only use standard Windows tools.

回答1:

findstr /L /v /X /g:remove.txt content.txt>result.txt

/X means "match lines exactly"

?L means "literally - not regex"

/v means "not -matching"

/g:filename is filename to use as string-(exclusion)-source

/I would make case-insensitive.
