I have an unexpected file named [
-- a left bracket -- in my /bin file on my Mac Powerbook. I'm running Catalina. When I cat
the file it looks like Apple certificate authority stuff. Most of it is unreadable, but has text in it like
Apple Certification Authority
and
PROGRAM:test PROJECT:shell_cmds-207.40.1 ??????i@[]missing ]!unexpected operator%s: %s%sclosing paren expectedargument expected%s: bad number%s: out of range)
Any idea what this could be? Seems suspicious to me -- like some source code in it based on the error messages. But don't want to just delete in case it is a file Apple needs.
