pipe out nothing (if prog doesnt have a no verbose mode)


This is a funny question, but would be highly useful for me. I have a program that has so silent/no verbose mode and I want to run it so that nothing gets printed out of the console or gets output to a file (this is because it prints out alot of info and slows down my comp) Ive been doing the usual:

$ program > output

just so that it is silent, but its getting to the stage where the output is getting very large! Is there something I could do to not let it printout to a file and still have it silent...?

Thanks in advance

It writes everything written to file descriptor 1 (stdout) to /dev/null (special write-only storage of great capacity) and file descriptor 2 (stderr) to descriptor 1 (stdout) which is written to /dev/null.
