Grep for windows


Old.txt contains

apple
orange
banana

And New.txt contains

apple
orange
banana
grape
lemon

I can access new contents which are added to New.txt using grep command.

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

Now, difference.txt contains

grape
lemon

In Windows, I have tried

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

to find the difference but it append contents of Old.txt too. How can I write equivalent command in Windows?


Solution

  • You can use DOS findstr with the following flags:-

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

    The command would be something like:-

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

    Now checking the file output using the type command; equivalent to cat in Linux, we see :-

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