findstr DOS Command's multiple string argument

findstr /v "black"  File1.txt

Above DOS command will display content of 'File1.txt' which are not matching string "black".

How to modify this command , if I need to filter words "black" and "white" ?


How do I filter words "black" and "white"?

The following command will display all lines containing "black" NOR "white":

findstr /v "black white" blackwhite.txt

The following command will display all lines containing "black" OR "white":

findstr "black white" blackwhite.txt

The following command will display all lines containing EXACTLY "black white":

findstr /c:"black white" blackwhite.txt

The following command will display all lines containing "black" AND "white":

findstr "white" blackwhite.txt | findstr "black"

Notes:

  • When the search string contains multiple words, separated with spaces, then findstr will return lines that contain either word (OR).

  • A literal search (/C:string) will reverse this behaviour and allow searching for a phrase or sentence. A literal search also allow searching for punctuation characters.

Example data file (blackwhite.txt):

red
black
white
blue
black white
black and white

Example output:

F:\test>findstr /v "black white" blackwhite.txt

red
blue

F:\test>findstr "black white" blackwhite.txt
black
white
black white
black and white

F:\test>findstr /c:"black white" blackwhite.txt
black white

F:\test>findstr "white" blackwhite.txt | findstr "black"
black white
black and white

If you need to display all lines with the words "black" or "white" then get rid of the /v in your command.

Try: findstr white File1.txt or findstr black File1.txt or findstr "black white" File1.txt

The /V operand will print all lines that DO NOT contain your search string.
