Windows 'findstr' command: Exclude results containing particular string

Question

To the command findstr str1 *.* I want to add something that will exclude the results which contain the string str2.

In Linux the way of doing it is to add | grep -v str2 (to grep str1 * of course). Is there an equivalent flag to -v in Windows?

Answer 1

Is there an equivalent flag to -v in Windows?

The equivalent to -v is /V.

/V         Prints only lines that do not contain a match.
