I just realized this too and tried to close stdout instead. tee complains about it but goes on with its business: cat foobar.img | sudo tee /dev/sdi >&-

- RJIb8RBYxzAMX9u 10y agoWhy's everyone so against dd? :-) If you're going to use tee, might as well not bother with cat at all[0]: $ sudo tee /dev/sdi >&- < foobar.img Or better yet, pv[1]; you even get a progress bar that way!

- mercora 10y agoThanks for the reminder :) I do fall quite often for the useless use of cat. But most of the time i also do not really care about it much. I did omit pv in believe tee will always be available but it is great and absolutely preferred when available.
