I have seen many examples of how to create a file through command line using a static name but I need to get it to show a dynamic name based off of my commands output. What I mean by this is the following:

I run the command npm -v and it returns 6.4.1 I can easily write that out to the inside of a file but I want the filename to be 6.4.1 if that is what the command returns. So if it returns 8.15.1 then the filename would be 8.15.1.

Any idea how to do that? I need this to be able to run on windows 7/10 machines so I can verify versions of npm and resolve version mismatches.

This previous question asked the more general question about the equivalent of bash backticks in the Windows commandline.

For your question, example syntax would be as follows:

for /f "usebackq tokens=*" %i in (`npm -v`) do echo %i > %i

The above would write the output of npm -v to a file with a name of the version of npm.
