NAME
       stdbuf  - Run COMMAND, with modified buffering operations for its stan‐
       dard streams.

SYNOPSIS
       stdbuf OPTION... COMMAND

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

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

       -i, --input=MODE
	      adjust standard input stream buffering

       -o, --output=MODE
	      adjust standard output stream buffering

       -e, --error=MODE
	      adjust standard error stream buffering

       --help display this help and exit

       --version
	      output version information and exit

       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 follow‐
       ing: 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.

EXAMPLES
       tail -f access.log | stdbuf -oL cut -d ' ' -f1 | uniq
       This will immedidately display unique entries from access.log

BUGS
       On GLIBC platforms, specifying a buffer size, i.e. using fully buffered
       mode will result in undefined operation.
