.IP 
.IP "-h" 
Displays a help message and exits\&.

used to play with buffer size\&.
.IP "-o" 
Don\&'t show summary\&.
.IP "-b \fIbufsize\fP" 
Use this buffer size, in bytes\&.
.IP "-r" 
Just show raw speed, no fancy stuff\&. And no summary\&.
.IP "-s \fIfile\fP" 
Write status to \fIfile\fP instead of stderr\&.
.IP "-S \fIfile\fP" 
Write status to \fIfile\fP instead of stderr\&.
.IP "-I" 
Use 1kB = 1000B, instead of the default 1024B\&.
.IP "-u" 
Don\&'t convet to units (kilo, Mega, etc\&.\&.\&.)
