View the rsync Progress during Transfer

When you use rsync for backup, you might want to know the progress of the backup. i.e how many files are copies, at what rate it is copying the file, etc.

rsync –progress option displays detailed progress of rsync execution as shown below.

$ rsync -avz --progress thegeekstuff@ /root/temp/
receiving file list ...

To find USB Speed from a terminal

The pv tool allows you to view the throughput of the data flowing through it. After installing the package, you could run a command like the following to see the write rate:

$ cat /dev/zero | pv > /media/some_usb/tmp123
203.1MiB 0:00:02 [100.2MiB/s] [ ]

For reading, perform the opposite operation using the newly-created tmp123 file:
$ cat /media/some_usb/tmp123 | pv > dev/null
