Usage: stdbuf OPTION... COMMAND 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. 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.
