Hi You mistyped /dev/null so created a file and filled the disk. Kelly

Huh ???

Huh ??? 1) "/dev/null" not "/dev/dull" 2) "if=/dev/null of=/dev/sdb" not "if=/dev/sdb of=/dev/null"

He did have them in the right order. "if=/dev/null of=/dev/sdb" would do nothing at all.

But the OP actually wanted "if=/dev/sdb of=/dev/null". I'm not sure that "if=/dev/null of=/dev/sdb" does much, but I wouldn't test it on a partition whose data I'd prefer not to lose:)

I was thinking of "dd if=/dev/urandom ...". I did this three weeks ago before backing up some systemd config files that I wanted to keep :( But the OP actually wanted "if=/dev/sdb of=/dev/null". I'm not sure that "if=/dev/null of=/dev/sdb" does much, but I wouldn't test it on a partition whose data I'd prefer not to lose :)

My favorite /dev/null story was the time someone apparently deleted the /dev/null file, then the next time someone redirected output to it, it was created, but as a regular file. The amount of confusion that caused was awesome:-).
