Title: pipe viewer
Post by: billium on April 09, 2016, 05:37:10 AM

I would like to have pipe viewer for monitoring dd.  As it is no longer a standard extension I will investigate making an extension.  Before I do, I was wondering why it was dropped.  Is it for a technical reason or nobody had any use for it?
Thanks.

You could download it from here:

http://tinycorelinux.net/4.x/x86/tcz/pv.tcz

..try it out and, if it works, it can be copied to the current repo.

Isn't that what "tee" is for?

Thanks very much for that Juanito, works great for me.
X86 up-to-date tinycore.

Looking at what tee does, it copies the o/p, whereas pv shows the progress through a pipe.
I did not know about tee and have never tried it. Tee also slows down the pipe, from what I have just read.

Tee lets you see the pipe contents, which is what I was thinking you wanted. You can use it to get clever by tee'ing to a fifo then having another program read the fifo and do stuff, or just watch stuff go by while you are saving a log too.
