    speedometer [options] tap [[-c] tap] ...
 
 

OPTIONS

-f filename [size]
Display download speed with progress bar. This option must be used if directly following another file tap without an expected size specified.
-i interval
Interval in seconds. Examples: 5 or 0.25". Default is 1.
-p
Use plain-text display (one tap only).
-rx iface
Display bytes received on network interface.
-tx iface

DESCRIPTION

Monitor network traffic or speed/progress of a file transfer. At least one tap option (-f, -rx, -tx) must be entered. Option -c starts a new column, otherwise taps are piled vertically.
