Grep for windows

Question

Old.txt 包含

apple
orange
banana

并New.txt包含

apple
orange
banana
grape
lemon

我可以访问添加到New.txtusing grep命令的新内容.

grep -Fxvf Old.txt New.txt > difference.txt 

现在,difference.txt包含

grape
lemon

在Windows中,我试过了

findstr /rvc:Old.txt New.txt > difference.txt 

找到差异,但它也附加了内容Old.txt.如何在Windows中编写等效命令？

Answer 1

您可以使用DOS findstr以下标志: -

/v   : Prints only lines that do not contain a match.
/g: file   : Gets search strings from the specified file.

该命令将类似于: -

C:\Users\dude\Desktop>findstr /v /g:Old.txt New.txt >difference.txt

现在使用type命令检查文件输出; 相当于cat在Linux,我们看到: -

C:\Users\dude\Desktop>type difference.txt
grape
lemon
