 .Sh NAME
 .Nm libstdbuf
 .Nd preloaded library to change standard streams initial buffering
 .Sh DESCRIPTION
 The
 .Nm
 library is meant to be preloaded with the
 .Ev LD_PRELOAD
 environment variable to as to change the initial buffering
 of standard input, standard output and standard error streams.
 .Pp
 Although you may load and configure this library manually,
 an utility,
 .Xr stdbuf 1 ,
 can be used to run a command with the appropriate environment variables.
 .Sh ENVIRONMENT
 Each stream can be configured independently through the following
 environment variables (values are defined below):
 .Bl -tag -width size -offset indent
 .It Ev _STDBUF_I
 Initial buffering definition for the standard input stream
 .It Ev _STDBUF_O
 Initial buffering definition for the standard output stream
 .It Ev _STDBUF_E
 Initial buffering definition for the standard error stream
 .El
 .Pp
 Each variable may take one of the following values:
 .Bl -tag -width size -offset indent
 .It Qq 0
 unbuffered
 .It Qq L
 line buffered
 .It Qq B
 fully buffered with the default buffer size
 .It Ar size
 fully buffered with a buffer of
 .Ar size
 bytes (suffixes 'k', 'M' and 'G' are accepted)
 .El
 .Sh EXAMPLE
 In the following example, the stdout stream of the
 .Xr awk 1
 command
 will be fully buffered by default because it does not refer
 to a terminal.
 .Nm
 is used to force it to be line-buffered so
 .Xr vmstat 8 Ns 's
 output will not stall until the full buffer fills.
 .Bd -literal -offset indent
 # vmstat 1 | LD_PRELOAD=/usr/lib/libstdbuf.so \\
     STDBUF_1=L awk '$2 > 1 || $3 > 1' | cat -n
 .Ed
 .Pp
-See also the manpage of
+See
 .Xr stdbuf 1
 for a simpler way to do this.

 .Sh HISTORY
 The
 .Nm
 library first appeared in
 .Fx 8.4 .
 .Sh AUTHORS
 .An -nosplit
 The original idea of the
 .Nm
 command comes from
 .An Padraig Brady
 who implemented it in the GNU coreutils.
 .An Jeremie Le Hen
 implemented it on
 .Fx .
