stdbuf - Run `COMMAND`, with modified buffering operations for its standard streams.

       Run `COMMAND`, with modified buffering operations for its standard streams.

       Mandatory arguments to long options are mandatory for short options too.

       If  MODE  is  'L'  the  corresponding stream will be line buffered.  This option is invalid with standard
       input.

       If MODE is '0' the corresponding stream will be unbuffered.

       Otherwise, MODE is a number which may be followed by one of the following:

       KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so  on  for  G,  T,  P,  E,  Z,  Y.   In  this  case  the
       corresponding stream will be fully buffered with the buffer size set to MODE bytes.

       NOTE:  If  COMMAND  adjusts  the  buffering  of  its  standard streams (tee does for e.g.) then that will
       override corresponding settings changed by stdbuf.  Also some filters (like dd and cat  etc.)  don't  use
       streams for I/O, and are thus unaffected by stdbuf settings.
