bug#54174: (MacOS Monterey 12.2.1: zsh): grep "string" * is interpreted as grep -V when directory has a filename "-Vfilename.ext" |

Ok. I understand it is not possible to make “-V “ instead of “-Vfilename”
because so many existing scripts rely on thatgrept works a certain way.
Maybe what is possible is to add a line to manual that explains that certain
filenames that are OK in modern OS might not work with grep.
I have used “-" sometimes to keep certain file at the top of directory
hierarchy. In this case I was organizing libraries and marked those that I was
not using with “-“.
Here is command-line example that you asked.
Even looked from the manual the simple example and did not see what I was doing
wrong (I did not read the whole manual.)
So if the program user interface cannot be changed maybe the manual could tell
that filenames that start with “-“ might require some additional quoting....

doing grep on that directory for a “string" did not find anything

grep just kept repeating something … FreeBSD
Finally, (with some help) I understood that grep interpreted “-Vfiename” as an
option -V and
gave the version info instead of doing grep “string” *
Maybe there is a way to add space after “-V “ and possibly also other options
that could be used as part of a filename in some operating systems?
