I've launched a .cmd file from somewhere in my %PATH% How can I know the location of the file?

Question

I can successfully run a .cmd file by typing its name (tsc in this case):

C:\Windows\system32>tsc --version
Version 1.0.3.0

It instantly prints the result and terminates.

There is no tsc in C:\Windows\system32, so presumably it is being launched somewhere from a location specified in my %PATH%. I've searched through the drive and found a bunch of tsc.cmd files. How can I know, which of them is being launched?

Answer 1

The where command in cmd will tell you what you want to know:

where tsc.cmd

In this basic invocation it is the equivalent of the Unix which, though where has additional options not in the Unix command.

Answer 2

Install Process Explorer.

Double-click on the tsc process will give all the information you need.
