# Description
Fixes: #9293
The problem is caused by `save` makes a `BufferWriter` for output file,
when external commands redirect it's output to a file, the content is
bufferred first...
To fix the issue, I'd like to introduce a `--no-buf` flag for `save`
command, and it's only used in redirection scenario.
Sorry it's hard to test against it in test, because it requires external
command to sleep or pause...
