How can I tell zsh to automatically flush the buffers when using
multiple redirections?
For instance, if I don't use any redirection, I get one line after the
other in STDOUT, but if I redirect STDOUT like this
prg >results >&2
I only get the results when the program terminates.

That's up to the program, `prg' in this case. All zsh does is open
the file. You might find the `script' command to be of some use, if
you can't modify the program.

Thanks, this works (as the program is a perl script, I could add
a "$| = 1;"). I was just a bit surprised because when there is no
redirection, the results are written to the screen one line after
the other, even with no "$| = 1;".
