stdbuf @var{option}@dots{} @var{command}
@end example
+@var{command} must start with the name of a program that
+@enumerate
+@item
+uses the ISO C @code{FILE} streams for input/output (note the
+programs @command{dd} and @command{cat} don't do that),
+
+@item
+does not adjust the buffering of its standard streams (note the
+program @command{tee} is not in this category).
+@end enumerate
+
Any additional @var{arg}s are passed as additional arguments to the
@var{command}.
@end table
-NOTE: If @var{command} adjusts the buffering of its standard streams
-(@command{tee} does for e.g.) then that will override corresponding settings
-changed by @command{stdbuf}. Also some filters (like @command{dd} and
-@command{cat} etc.) don't use streams for I/O, and are thus unaffected
-by @command{stdbuf} settings.
