Yep, and it depends on the contents of your current directory.

Try:
echo grep 'BKOPS' *

to see what the shell globbed the * into, and why the resulting command 
line resulted in something that grep doesn't like.

Then read this FAQ (it's for coreutils, but it applies equally well to 
grep): 
https://www.gnu.org/software/coreutils/faq/#I-have-a-file-_0027_002df_0027-and-it-affects-rm_002e 
(several other FAQ on that page also talk about globbing issues, so it's 
a good read)
