Provide Estimated Time And Connection Speed
SCP command also provides estimated time and connection speed for transferring file. You can achieve this by using
-p option with SCP command.
scp -p Filename.zip [email protected]:.
The output should look like:
[email protected]'s password: Filename.zip 100% 9800KB 178KB/s 00:55

In below example, filename.zip file from system
139.168.x.x to the specified directory of
scp [email protected]:/files/filename.zip [email protected]:/path/to/directory/
You will be also prompted for passwords of both systems for transferring data from one system to another.
