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?
