FINDSTR - get range of lines and text and put it to a file-CodePudding

This command works fine - getting a range of lines and text

for /r %i in (*) do type %i|findstr/n ^^|findstr " ^30[6-9]: black blue

But the following command won't put the output to a file

for /r %i in (*) do type %i|findstr/n ^^|findstr " ^30[6-9]: black blue >>save.txt

What is the syntax that I need to use?

(@for /r %i in (*) do @type %i|findstr/n ^^|findstr " ^30[6-9]: black blue")>>x.txt

The search-strings need to be quoted - the end-quote is missing. The @s suppress the command-echo.

The enclosing parentheses are required if you use a single > as a redirector, which creates a new file. If you use >> then they are optional. Without them, each individual findstr's output is appended to the file, which opens/closes the output file many times. WIth them, it's the for output that's redirected to the file.
