NAME

	tput – measure read throughput

SYNOPSIS

	tput [ –b buflen ] [ –p ]

DESCRIPTION

Tput continuously reads standard input writing throughput statistics to standard error. The throughput value is calculated and written once per second and automatically scaled to kilo–, mega– or gigabytes. When the –p flag is specified, tput will write the data read to standard output (the default is to discard the data). A read blocksize (default is the iounit(2) of file–descriptor) in bytes can be given with the –b buflen option.
