Support scanning multiple specified files on the command line

[MVrachev]

Hi, how can I scan multiple files?

I don't want to scan a whole folder I want to scan only a few specific files.
I want to achieve something like that: detect-secrets scan test.js test.yaml but right now when I run it I get:

I think (from researching a little on the code out of curiosity) that it's only scanning the first argument (file or directory). Maybe this one is the 'offending' function:

detect-secrets/detect_secrets/core/usage.py

Line 120 in 1f3322c

def _add_initialize_baseline_argument(self):

As it's using '?' nargs that reads only one argument if possible [0]. I'm sure that @domanchi or @KevinHock can throw more light on this issue.

That's accurate. Shouldn't be too hard to modify this such that it can scan multiple files with the command line invocation you suggested: https://github.com/Yelp/detect-secrets/blob/master/detect_secrets/core/baseline.py#L37

I closed it by mistake.
