This is a mechanism for showing copy progress. It is a Bourne shell script, intended to be portable: Theiling Online: ASCII bar the author calls it small, the version that I have used is almost 700 lines long.

Hi.
In re-visiting the web page for pv, it struck me that I could use it in a current application.
I keep several virtual machines in a large machine -- a "VM server" as it might be called. I often take snapshots with the VMWare server. However, at longer intervals I want to save the state of each VM. For that, the VM is off-powered, and I run a shell script to tar the files that VMWare creates and gzip the resulting tar file. This often takes more than 10 minutes, so I find it useful (and comforting) to see the progress.
The output looks like this after the tar file for distribution GNU/Linux mint has been created and compressed:
the size of the tar file was estimated with du, and 2 instances of pv were used, 1 for the tar, which produces the first progress line. The size of the data for the second process cannot be estimated, so in place of a completion bar, the symbols "<=>" are simply moved back and forth within the brackets to show activity.
The pv code is quite clever, and uses cursor position commands to move back and forth between the 2 one-line displays for updating. The first line includes measures for amount copied, time used, rate of transfer, completion bar, and ETA.
The relevant small bit of script that gets this accomplished is:
I'm impressed with the thought that went into the design of pv. In my system, pv was in the repository (Debian).
