NAME

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

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

SYNOPSIS

stdbuf [-i|--input] [-o|--output] [-e|--error] [-h|--help] [-V|--version] <command>

DESCRIPTION

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

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

OPTIONS

-i, --input=MODE

adjust standard input stream buffering

-o, --output=MODE

adjust standard output stream buffering

-e, --error=MODE

adjust standard error stream buffering

-h, --help

Print help

-V, --version

Print version

EXTRA

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.
