stdbuf
STDBUF(1) BSD General Commands Manual STDBUF(1)NAME
stdbuf -- change standard streams initial buffering
SYNOPSIS
stdbuf [-e bufdef] [-i bufdef] [-o bufdef] [command [...]]
DESCRIPTION
stdbuf is used to change the initial buffering of standard input, standard output and/or standard error streams for command. It relies on
libstdbuf(3) which is loaded and configured by stdbuf through environment variables.
The options are as follows:
-e bufdef
Set initial buffering of the standard error stream for command as defined by bufdef (see BUFFER DEFINITION).
-i bufdef
Set initial buffering of the standard input stream for command as defined by bufdef (see BUFFER DEFINITION).
-o bufdef
Set initial buffering of the standard output stream for command as defined by bufdef (see BUFFER DEFINITION).
BUFFER DEFINITION
Buffer definition is the same as in libstdbuf(3):
"0" unbuffered
"L" line buffered
"B" fully buffered with the default buffer size
size fully buffered with a buffer of size bytes (suffixes 'k', 'M' and 'G' are accepted)
EXAMPLES
In the following example, the stdout stream of the awk(1) command will be fully buffered by default because it does not refer to a terminal.
stdbuf is used to force it to be line-buffered so vmstat(8)'s output will not stall until the full buffer fills.
# vmstat 1 | stdbuf -o L awk '$2 > 1 || $3 > 1' | cat -n
SEE ALSO libstdbuf(3), setvbuf(3)HISTORY
The stdbuf utility first appeared in FreeBSD 8.4.
AUTHORS
The original idea of the stdbuf command comes from Padraig Brady who implemented it in the GNU coreutils. Jeremie Le Hen implemented it on
FreeBSD.
