It would not be logical, since what you type is copied back to the console, you would end up with a blank line before each new prompt. -- Guillaume Cottenceau - http://mandrakesoft.com/~gc/

Uh... you're different...
Basically, 'cat' takes its STDIN and copies it to STDOUT.

Yeaaah! you got it!!! :-))
[gc@obiwan ~] printf 'plop'
[gc@obiwan ~] printf 'plop\n'
plop
[gc@obiwan ~] printf 'plop\n\n'
plop

Yes, it is a feature. zsh must know the exact position on the screen, else output may be messed. promptcr makes sure the pscreen position is known. The same sort of problem happens if prompt contains escapes that move cursor. You may be badly surprised. Not having final newline in tty text output is not common; and catting binary files on tty is not the best way to see contents. -andrej

What happens is that the shell outputs a carriage return before printing
the prompt. This is the default behaviour and it explains what you see.
zsh has a way around this though:
zsh$ echo -n ioqzejcoiqjzegf >meuh
zsh$ cat meuh# Nothing printed, the CR eats all chars
zsh$ unsetopt promptcr # Magic!
zsh$ cat meuh
ioqzejcoiqjzegfzsh$
I don't know if bash can also do so, but I guess it can.

Do you use zsh? There's an option (from Chmou) that forces zsh to do this, it's
a feature not a bug ..

Uhm, shouldn't cat display every file out there? I thought that cat is also
able to handle binary files with no problems, but I can see that this may
break if this bug isn't fixed.

Ah! So the prompt simply overwrites the output because the file isn't
newline terminated?

It's not newline terminated... so what?

I suspect you are hitting the same bug which appeared before when
discussing bash problem. Try to terminate your file with newline instead,
and you'll have some idea what happened.

[Cooker] Cannot cat file
Hi!
For some strange reason, I cannot (even as root) 'cat' this file:
33018,ntUd5@dEDeBKtly{
I also attached it. When I cat it, it simply doesn't print anything?!
However, less is able to display the files contents.
