I am trying to list file names that contains a give string using this command:
$ find . -name "*" -maxdepth 1 -exec grep "*mystring*" {} \;

I get lots of messages like the ones below:

grep: Cannot open file './NTUSER.DAT': Device busy
grep: Cannot open file './ntuser.dat.LOG': Device busy

My quesiton is:
1- Is the above command correct?
2- Is there a way to get rid of the messages and only keep the files that were opened OK?

Thanks,
