NAME
unbuffer - unbuffer output
SYNOPSIS
unbuffer program [ args ]
INTRODUCTION
unbuffer disables the output buffering that occurs when program output is redirected. For example, suppose you are watching the output from a fifo by running it through od and then more. od -c /tmp/fifo | more You will not see anything until a full page of output has been produced. You can disable this automatic buffering as follows: unbuffer od -c /tmp/fifo | more When you have a pipeline, unbuffer must be applied to each element except the last (since that doesn't have its output redirected). Exam- ple: unbuffer p1 | unbuffer p2 | unbuffer p3 | p4
BUGS
The man page is longer than the program.
