       unbuffer - unbuffer output

       unbuffer program [ args ]

       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

	    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).  Example:

	       unbuffer p1 | unbuffer p2 | unbuffer p3 | p4

       The man page is longer than the program.
