When I type dd if= then hit TAB to complete, the file name is added, but the if= portion vanishes (and of= too, for that matter).



So for example, instead of



# dd if=input_file.iso of=/dev/sdb


I get



# dd input_file.iso /dev/sdb


when using TAB completion. What is going on?

  • Which shell are you using? Some of them are using dark magic these days... like bash tab completion helpers that just mess things up in completely unpredictable ways.
