As pludi told you, you should learn about the shell before you start writing shell-scripts.

Just try "echo /bin/*", you'll see where the alsacard comes from.

Your script will only see the * if...

Thanks, zxmaus. I'd ignored that one because of the NFS, and also the files in my case have been around for months without change, to the file and all directories above.

access("/softih/fatwire/Shared/elements/Roularta/Query/Template/Sql/2_0.jsp", 04) = 66

}' /etc/group

grep -E '^(.*[^N][^o][^t] )?Ok to Proceed' a.txt && touch Go.txt
