linux - tmux: confusing behavior with redirection and piping -

here trying - copy tmux buffer contents file.

first attempt:

$ tmux show-buffer > myfile

this "hangs", in never completes.

however, can like:

$ tmux show-buffer | cat > myfile

then try else, use 'tee' command instead:

$ tmux show-buffer | tee myfile  .. ..  tee: write error

it displays "tee: write error" @ end, .. indicating part of buffer prints, not (as should) print whole buffer. file has entire contents, however.

i believe has how tmux show-buffer works , it's relation redirection , piping behavior. know more this?

this seems have been issue older tmux version (1.5). 1.8, works fine.
