I have a text file with a list of macro names (one per line). My final goal is to get a print of how many times the macro's name appears in the files of the current directory.

The macro's names are in C:\temp\macros.txt.

type C:\temp\macros.txt in the command prompt prints the list alright.

Now I want to pipe that output to the standard input of findstr.

type C:\temp\macros.txt | findstr *.ss (ss is the file type where I am looking for the macro names).

This does not seem to work, I get no result (very fast, it does not seem to try at all). findstr <the first row of the macro list> *.ss does work.

I also tried findstr *.ss < c:\temp\macros.txt with no success.
