nobuf 1 user commands djbwares
nobuf run a program without stdio block buffering
`nobuf` subprogram args

## Description

`nobuf` subprogram is similar to subprogram with one exception. If subprogram uses stdio, it will use block buffering rather than line buffering when its output is redirected; `nobuf` subprogram will always use line buffering.

Internally, `nobuf` obtains a new pty and runs subprogram under it, transparently forwarding input and output. `nobuf` initializes the pty to remote mode, where tty processing is disabled, input is flow-controlled, and end-of-file is passed through to subprogram.

`nobuf` is a synonym for `ptyget` `ptyio` -r `ptyspawn` -23x. ptyspawn 1 options may be used with `nobuf`.

## History

`nobuf` was originally part of Daniel J. Bernstein's ptyget toolset in 1996.
