Синопсис (Synopsis)

stdbuf OPTION... COMMAND

Описание (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
       following: KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on
       for G, T, P, E, Z, Y.  Binary prefixes can be used, too: KiB=K,
       MiB=M, and so on.  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 example) then that will override corresponding
       changes by 'stdbuf'.  Also some filters (like 'dd' and 'cat'
       etc.) don't use streams for I/O, and are thus unaffected by
       'stdbuf' settings.

Примеры (Examples)

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

Ошибки (баги) (Bugs)

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