speedometer − measure and display the rate of data across a network connection
speedometer [options] tap [[−c] tap] ...
−b |
Use old blocky display instead of smoothed display even when UTF−8 encoding is detected. |
−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
Display bytes transmitted on network interface.
−z |
Report zero size on files that don’t exist instead of waiting for them to be created |
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.
