@koalaman i have possible fix for simple cases of this:
[ -"$op" "$file" ]
parses, but triggers SC2058: Unknown unary operator
We can probably change SC2058 to check for this case too, what do you think?
from shellcheck.
I think the best thing for this case would be to keep parsing the same, but to allow continuing on failure. That way you can do whichever dynamic magic you want, and if ShellCheck doesn't get it, you can just disable it.
I don't think that fixing the case of -"$op"
by itself is sufficiently useful if op='-n'; [ "$op" foo ]
doesn't work.

It seems that using test <expr>
instead of the equivalent [ <expr> ]
allows shellcheck to correctly parse the command.
